Designing of Rectangular Microstrip Patch Antenna for IMT Advance (4G) with Best Impedance Matching

This paper describes the best impedance matching for wireless microstrip patch antenna i.e IMT Advance (4G) applications. A good impedance matching between the line and patch without any additional patching elements heavily depends upon feeding technique used. This Paper describes proximity coupled feeding technique and gives a better understanding of design parameters of an antenna and their effect on return losses, bandwidth, VSWR and resonant frequency. Finally simulation is done using design software HFSS. The proximity coupled feeding technique provides a wide bandwidth with best impedance matching and minimum return loss.
