Abstract
In this paper, a combined and compact double H-shaped X-band microstrip patch antenna is designed for bandwidth enhancement. The proposed rectangular antenna is fed by a 50 Omega microstrip line. FR-4 (Lossy) is used as a substrate to design the recommended antenna which has a condensed structure of 18x20mm(2). The operating zone of this antenna is within 8.4 to 13.6GHz that covers the entire X-band. The gain of the antenna is 5.29dBi which symbolizes its ability to work for mobile communication. This double H-shaped antenna has a return loss is -31.53dBi and an efficiency of 82%. Regarding the antenna, the results are obtained in terms of return loss, gain, radiation pattern and efficiency. The prospective antenna has a compact size, good radiation characteristics and good time domain behavior to mollify the obligation of the recent wireless communication system.
