Design and experimental analysis of beam repositioning system in microstrip patch antenna array using dumbbell shaped Defected Ground Structure (DGS) for Wireless application (2.4 GHz) was carried out in this study. For the practical application of this study phase shifters are used to control the relative position of the main-lobe direction. DGS has characteristics of disturbing current distribution which leads to phase variation. In our antenna, these dumbbell shaped DGS are engraved at different positions over the ground plane to achieve phase shifting of main-beam. The parameters of antenna such as gain reflection co-efficient, bandwidth are determined and compared with the antenna without DGS. Every position at which the dumbbell shaped DGS was placed, the radiation pattern was measured and compared among them. Further, it’s also observed that simulated antenna with DGS has the Bluetooth application in ISM short-range band.

But due to its resonant nature microstrip antennas have some considerable drawbacks like narrowband performance. Extensive study has been carried out on microstrip patch antennas in the recent past, but it still have large scope for improvement in the near future. To overcome narrow bandwidth problem, number of methods and techniques have been suggested and investigated, keeping in mind that the basic advantages of microstrip antenna should not be altered such as low profile, light weight, low cost and simple printed circuit structure. The area of investigation includes modification in geometrical shape of the antenna, use of resonators, use of dipole, and many other parameters.

Microstrip antennas or patch antennas are popular for their attractive features such as low profile,
low weight, low cost, ease of fabrication and integration with RF devices. Micro strip antennas have been found
favorable because they are inexpensive to manufacture and compatible with monolithic microwave integrated
circuit designs (MMIC). They are usually employed at UHF and higher frequencies because the size of the
antenna is directly tied to the wavelength at the resonance frequency. A Microstrip or patch antenna is a
narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an
insulating dielectric substrate with a continuous metal layer bonded to the opposite side of the substrate which
forms a ground plane. The most commonly employed microstrip antenna is a rectangular patch.
The major disadvantages of Microstrip antennas are lower gain and very narrow bandwidth. Microstrip patch
antennas have some drawbacks of low efficiency, narrow bandwidth (3-6%) of the central frequency. Millimeter
wave technology being an emerging area is still much undeveloped. As micro strip antennas have found wide
variety of application areas, a number of techniques are evolved to improve its limited bandwidth. A good
approach to improve the bandwidth is increasing the thickness of substrate supporting the micro strip patch.
However problems exist on the ability to effectively feed the patch on a thick substrate and the radiation
efficiency can degrade with increasing substrate thickness. A substantial research needs to be done in this area
as its applications are numerous. The radiation patterns and S11 performance are used for the analysis of the
different configurations. In the present endeavor a rectangular patch antenna is designed on thick substrate and simulated using MATLAB software and configuration on different dielectric susbstrates was used .

Rectangular and circular antennas design for Bluetooth applicationsTELKOMNIKA JOURNAL
The most researched and examined aspect of the communication system is the wireless connection. Without learning how to operate and use different types of antennas, your knowledge is incomplete. Microstrip patch antenna research has advanced significantly in recent years. When compared to standard antennas, microstrip patch antennas provide additional advantages and opportunities. It is of low volume, light weight, low cost, low appearance, compact and easy to manufacture. This study investigates the differences between rectangular and circular patch antennas. For Bluetooth applications, the center frequency of 2.4 GHz was chosen as the optimal resonant frequency. On a flame retardant (FR-4) epoxy substrate, the antenna dielectric constant is 4.4. Above the ground the base rises 3.6 mm. For the simulation process, high frequency simulation software (HFSS 15) is used as the program design. Antennas 1×1, 1×2, and 1×4 are designed for both circular and rectangular antennas. A comparison was made for both types of antennas and voltage standing wave ratio (VSWR), return losses, gain, directivity and half power beam width (HPBW) were found, and the feature of the rectangular antenna was shown.
In this paper a compact, flexible, Multiband antenna is designed. It is having flexible Substrate of photographic paper which makes the antenna conformal. The antenna with two U slots cut in radiating patch is offset fed by microstrip lines gives the multiple bands of WLAN/WIMAX Application and two parasitic Elements improves the bandwidth of a typical microstrip antenna. The Measured results shows that the antenna resonates between Frequency band 2.10-2.95 GHz, 3.35-3.54 GHz and 5.04-6.0Hz.which are used for application such as Bluetooth, Wi-Fi, Zigbee, ISM 2.4GHz,WLAN WiMAX, and WLAN 5.2GHz.

The suggested antennas' resonance frequency ranges are 2.43 GHz, 5.24 GHz, and 9.61 GHz. The planned CMPA is made up of two circle-shaped slots cut into the radiating patch. The whole structure is supplied via a microstrip feed line and analysed using CST Studio's electromagnetic simulator, which is based on finite integral technique (FIT). To check the structure, the return loss, radiation pattern, voltage standing wave ratio (VSWR), and gain are all examined. The structure's ideal dimensions are determined using a parametric study of three factors: feed position, feed breadth, and ground size. The proposed CMPA is capable of operating in several bands and has good matching impedance in all of them.
5G Fixed Beam Switching on Microstrip Patch Antenna IJECEIAES
5G technology is using millimeter-wave band to improve the wireless communication system. However, narrow transmitter and receiver beams have caused the beam coverage area to be limited. Due to propagation limitations of mm wave band, beam forming technology with multi-beam based communication system, has been focused to overcome the problem. In this letter, a fixed beam switching method is introduced. By changing the switches, four different configurations of patch array antennas are designed to investigate their performances in terms of radiation patterns, beam forming angle, gain, half-power bandwidth and impedance bandwidth at 28 GHz operating frequency for 5G application. Mircostrip antenna is preferred due to its low profile, easy in feeding and array configurations. Three different beam directions had been formed at -15°, 0°, and 15° with half-power bandwidth of range 45˚ to 50˚.
In the present paper a circular slot rectangular microstrip loaded antenna is proposed. The obtained bandwidth of rectangular microstrip antenna is improved up to 46.92%. The proposed antenna has frequency band in the frequency range 1.979 GHz to 3.192 GHz this frequency band is suitable for WLAN / WiMAX and other wireless communication applications. The microstrip antenna suffers from narrow bandwidth hence the present work provide an alternative solution to increase the bandwidth. The gain has been improved up to 4.68dBi and antenna efficiency is 97.63%. The proposed slot loaded Microstrip antenna is fed by 0.3 mm line feed. The proposed antenna is simulated by IE3D Zealand simulation software based on method of moments.
TRI-BAND MICROSTRIP PATCH ANTENNA FOR S-BAND NANO SATELLITE APPLICATION USING...ijsrd.com
It's the generation of tiny satellites which basically needs all its components to be miniature. The product proposed here is one such component, a tri band micro strip patch antenna operating at 2.6GHz, 3.6GHz S-band frequencies and 5.8 GHz. This real-time project work deals with a rectangular patch antenna operating at different frequencies working for various applications. The proposed S-Band Patch antenna is being designed and simulated using HFSS software. Obtaining optimum bandwidth efficiency by choosing suitable size without affecting any other parameters of the antenna is the challenge taken over in this project. The low profile, less weight patch antenna has antenna element of physical dimension 40x40x2.6mm .The substrate material being used is Alumina with dielectric constant 9.6. This antenna is designed to be used for TTC and payload downlink purposes. The designed patch array antenna meets all the parametric needs for a Polar orbiting satellite at Low Earth Orbit (LEO) region.
Design of Micro strip Antenna in Ism Band with Polarization Diversity and Fre...paperpublications3
Abstract: In the modern world especially during the last two decades, Wireless communications has been developed widely and rapidly. In future, development in personal communication devices will provide image, speech and data communications at any time, and anywhere around the world. It shows that the future communication terminal antennas must meet the requirements of multi-band or wideband operations to cover the frequency band of operation. Frequency agile antennas in ISM band (2.4-2.4835) GHz that support diversity polarization provides excellent performance for applications including multifunction radar, space-based platforms, wireless communications, and personal electronic devices. To reduce the transmission losses, matching in polarization in both the transmitter and receiver antennas is very much important. In this paper we will design two microstrip antenna one with linearly polarized and other with circularly polarized in 2.4 GHz ISM band with frequency agility in 2.4-2.4835 GHz. In both the design single feeding is used. This paper presents a new design for a linearly polarized antenna based on rectangular microstrip patch. Circular polarization is generated by truncating two opposite edges from a rectangular patch antenna. The truncation splits the field with equal magnitude and 90° phase shift into two orthogonal modes. Both the antennas are simulated with high frequency simulating software (HFSS).

Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
