Parametric Analysis of Single Element U Slot Microstrip AntennaIJSRD
In wireless communication system antennas are the most important element for creating communication link between source and destination. Microsrtip antennas are used for mobile and other satellite communication application because of their light weight, low power handling capacity and low profile. The modern mobile communication system requires high gain, wide bandwidth and minimal size antennas that are capable of providing better performance over a wide range of frequency spectrum. This requirement leads to the design of microsrtip patch array antenna. This paper proposes the parametric analysis of single element U slot MSA. Low dielectric constant substrates are generally preferred for maximum radiation. Thus it prefers FR4 as a dielectric substrate. Desired patch antenna design is simulated by using high frequency simulation software and patch antenna is designed as per requirement. Antenna dimensions such as Length (L), Width (W), and substrate dielectric constant and parameters like Return Loss, Gain, impedance and current distribution are calculated using CAD-FEKO. The antenna has been design to be operated in the range of 8-12GHz. Hence this antenna is highly suitable for X-band applications.

This paper presents the design of wideband frequency reconfigurable metamaterial antenna with double H slots. The design is based on the idea of composite right/left-handed transmission line (CRLH-TL) technique. Bandwidth enhancement was achieved by utilizing series left-handed capacitor CL transmission line parameter. The design has several outstanding advantages which include efficient bandwidth to cover many lower Application bands with multi frequency operation characteristics. A comprehensive analysis and simulation were done by using computer simulation technology (CST) software to determine the performance and efficiency of the proposed antenna. From the result obtained, the antenna aquired bandwidth range which covered (2.3-5.2) GHz which is equivalent to 77% fractional bandwidth. The wideband antenna was reconfigured by using frequency reconfiguration technique. From the reconfiguration results, the antenna can be switch from wideband to two single bands which resonate at 2.4 GHz and 4.2 GHz and to dual band which resonate at 2.4 GHz and 4.2 GHz. The realized peak gain at 2.4 GHz is 2.28 dBi and 2.58 dBi for E and H field respectively. The maximum efficiency of 96% was obtained. The antenna can be use for WLAN, proposed lower 5G band and cognitive radio system for frequency sencing.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
