Abstract

In this paper, design of a quarter wave transformer-fed circular patch antenna is presented. The maximum size of proposed antenna is 25.4 mm by 25.4 mm. The substrate material used for this antenna has thickness of substrate 0.762 mm and relative permittivity epsiv_r 3.2. The design frequency of the antenna is 10 GHz. By selecting optimum parameters of proposed antenna, the measured return loss of proposed antenna at design frequency (10 GHz) is -24 dB. A novel 3-stub broad-band matching network is described, which enhances the bandwidth by a factor of 2. The simulated and measured radiation patterns show that the antenna functions as expected, with a gain of 7.52 dBi at 10 GHz. The proposed antenna should be useful for X band communication systems
