Query: Radiation Pattern of Patch Antenna with Slits   The Microstrip antenna has been commercially used in many applications, such
as direct broadcast satellite service, mobile satellite communications, global
positioning system, medical hyperthermia usage, etc. The patch antenna of the
size reduction at a given operating frequency is obtained. Mobile personal
communication systems and wireless computer networks are most commonly used
nowadays and they are in need of antennas in different frequency bands. In
regulate to without difficulty incorporate these antennas into individual
systems, a micro strip scrap transmitter have been preferred and intended for a
convinced divergence. There is also an analysis of radiation pattern, Gain of
the antenna, Directivity of the antenna, Electric Far Field. The simulations
results are obtained by using electromagnetic simulation software called feko
software are presented and discussed
