Bandwidth Enhancement for Microstrip Patch Antenna with Microstrip Line Feed

A new compact, wideband micro strip patch antenna with a micro strip line feed is presented in this paper. This antenna structure is realized on a glass epoxy substrate with dielectric constant 4.2, with thickness of 1.6 mm and finite ground plane. Using IE3D software package of Zeland, according to the set size, the antenna is simulated. This antenna is composed of a c-shape patch and is fed by a 50 ? micro strip line. The antenna size is very compact (40 mm x 60 mm x 1.6 mm) and covers 1.73 GHz to 2.23 GHz. The computer simulation results show that the antenna can realize wide band characters. With adjusted parameters, it exhibits a broad impedance bandwidth (VSWR = 2) of about 25%.
