Analysis of U-slot loaded truncated corner rectangular microstrip patch antenna for broadband operation

摘要

An analysis of broadband truncated corner rectangular microstrip patch antenna loaded with U-slot is presented using equivalent circuit approach based on cavity model. The U-slot and a pair of truncated corner are employed in a rectangular patch to achieve about 80.41% measured impedance bandwidth covering frequency range 2.58-6.05 GHz. It is found that impedance bandwidth highly depends on the truncated corners as well as slots dimensions. The other parameters of the proposed antenna are also studied and compared with the without U-slot truncated corner patch antenna. The maximum gain and efficiency of the proposed antenna are 9.78 dBi and 89.68%, respectively. The theoretical results are compared with simulated and measured results and found in good agreement.
