Abstract:
The thesis is the outcome of the experimental and theoretical investigations carried out on a novel slotted microstrip antenna.The antenna excites two resonance frequencies and provides orthogonal polarization. The radiation characteristics of the antenna are studied in detail. The antenna design is optimized using IE3D electromagnetic simulation tool. The frequency-Difference Time-Domain (FDTD) method is employed for the analysis of the antenna.The antenna can be used for personal and satellite communication applications.

Abstract:
A novel reconfigurable, single feed, dual frequency, dualpolarized
operation of a hexagonal slot-loaded square mwrostrip antenna
is presented in this paper. A pin diode incorporated in the slot is
used to switch the two operating frequencies considerably, without significantly
affecting the radiation characteristics and gain. The proposed
antenna provides a size reduction up to 61% and 26% Jor the two resonating
frequencies, compared to standard rectangular patches. This design
also gives considerable bandwidth up to 3.3% and 4.27%, for the two
frequencies with a low operating frequency ratio
