Abstract: - Microstrip patch antennas have been widely used in
a various useful applications, due to their low weight and low
profile, conformability, easy and cheap realization. The multi
feeding techniques is used to increase the impedance
bandwidth and to improve the radiation performance of
microstrip antennas. In this paper, an attempt has been made
to investigate proposed microstrip antenna structure i.e. the
broadband aperture coupled Microstrip antenna, using dual
feed (with and without E shaped patch and equal and unequal
slot) and three feed technique. The simulation results of the
broadband antenna and comparison of different types of
antenna structure is described.
