HFSS are used for the simulation and design calculations of
the microstrip antennas. The return loss, VSWR and radiation
pattern are evaluated. Using HFSS simulation software
proposed antenna is designed/simulated and optimized. The
effectiveness of the proposed designs is confirmed through
proper simulation results.
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.
