ABSTRACT
In this paper dual band Planar Inverted F Antenna (PIFA) is presented for mobile handset
applications at dual frequencies. PIFA is a flat structure, simple and easy to fabricate. The idea of
U-shaped slot technique is introduced into the basic rectangular patch antenna for higher GSM
frequency. The impedance bandwidth covers GSM 900 and GSM 1900 bands. The PIFA covers
a bandwidth of 31.9MHz (0.88-0.911GHz) or about 3.5% with respect to the resonance
frequency at 0.89GHz. For the higher resonant mode the impedance bandwidth is 112.7MHz
(1.873-1.985GHz) or about 5.83% with respect to resonance frequency of 1.93 GHz. The PIFA
has a gain of 2.59dB and 5.12dB at lower and higher resonating frequencies respectively. PIFA
is analyzed using High Frequency Structure Simulator (HFSS).

ABSTRACT
There are various patch antennas used for Wi-Fi and Wi-MAX applications. But, the problems
with them are low gain, low power handling capacity and hence, conventional yagi-uda antennas
are used. Conventional yagi-uda antennas are used in applications where high gain and
directionality are required. Generally, numbers of directors are added to increase gain of these
antennas. But, here we present modified yagi-uda antennas, in which the gain and bandwidth can
be enhanced by not adding additional directors.
In this paper, we initially discuss the designs of various yagi-uda antennas with uniform, non-
uniform spacings between directors and then we discuss their gain and bandwidth enhancement
by various approaches. Simulation results show that, the proposed techniques can enhance gain
as well as bandwidth when compared with the traditional yagi-uda antennas.

Technology, Pollachi.
ABSTRACT
Slot antenna is designed with microstrip feed line for Wireless Local Area Network (WLAN)
applications. The first patch is designed as a rectangular shape and the other is designed as an
inverted L shape. The antenna is printed on a FR4 substrate with a thickness of 0.8mm and
relative permittivity of 4.6. The resulting antenna is found to have a compact size of
22.75x22mm2. It offers dual band characteristics with -10dB return loss and it radiates in
omnidirectional pattern. The antenna receives RF signals which are converted into DC power by
connecting it through the matching circuit, rectifier and voltage multiplier. Matching circuit is
needed for matching the impedance of the antenna and the impedance of the rectifier. Rectifier
uses schottky diode (HSMS 2850) which has high switching speed and low forward voltage
convert the input RF signal received by the antenna into suitable DC supply voltage. The
produced DC voltage can be doubled by using voltage doubler. The output power from the
voltage doubler is given to low power devices for charging. These designs are simulated by using
ADS 2011 (Advanced Designs System) software.

12. THE EFFECTS OF CONDUCTIVITY OF THE MATERIALS ASSOCIATED
WITH THE WEDGES ON THE LOSS BY DIFFRACTION

ABSTRACT
Radio wave signals do not travel in a straight line path. There may be some obstacles between
the source and the destination which cause diffraction, reflection, scattering and attenuation.
There are some types of obstacles such as knife edge, wedges and round edges. This paper shows
the diffraction loss caused by wedges based on Uniformal Theory of Diffraction (UTD) given in
(ITU-R Recommendation P.526-12) using Matlab software. It could be said that this is an
important method because radio waves travel over wedge shaped roofs of buildings and corners
of the buildings. In addition this diffraction loss changes for both roofs and corners for a
particular obstruction material. Furthermore, the electrical properties of the wedge shaped
obstacles are affecting the diffraction loss such as conductivity and dielectric constant. The result
shows that higher conductivity leads to have a higher amplitude oscillation at the receiver.

ABSTRACT
A Microstrip Patch Antenna is a type of radio antenna with a low profile, which can be mounted
on a low surface. It is a narrow band, wide-beam fed antenna fabricated by etching the antenna
element pattern in metal trace bonded to the dielectric Substrate such as a printed circuit board
with a continuous metal layer bonded to the opposite side of the substrate which forms a ground
plane. The main aim of this work is to design, develop and test the Printed Circuit antenna
(Microstrip Patch antenna) suitable for use in L-band frequency range of 1-2GHz. This study
also emphasizes on simulation of micro-strip patch antenna using IE3D software to simulate &
study the radiation pattern & other radiation pattern parameters and comparison with
specifications/requirements. Co-axial Feed technique was adopted and the location of the feed
point was varied within the radiating patch to arrive at the point of minimum return loss. This
work is also focused on characterization of fabricated antenna in view of parameters like VSWR,
Antenna efficiency, Axial ratio, Gain and radiation pattern.

ABSTRACT
In the current paper, mono and multi EBG structures for wider bandwidth are presented. For
every EBG mentioned in this paper, metallic patches of regular shapes are selected as unit
elements and these patches are altered to get additional inductance and capacitance which
provides lower cut-off frequency and large bandwidth. The surface wave attenuation of EBG
structures are juxtaposed with conventional EBG of mushroom type. The variation of
transmission response due to unit element size, via diameter and distance between unit elements
is shown. Out of these proposed EBG’s the square patch is small, the fractal EBG has wider
bandwidth. The square patch with mono disconnected loop type slot and the fractal are multi
band. The designing of microwave circuits and the antennas can be done using these EBGs.
