摘要
In this article, analysis of slot loaded compact rectangular patch antennas have been presented theoretically using circuit theory concept. The theoretical investigations of L-strip fed slot loaded compact rectangular microstrip patch antenna parameters such as return loss, VSWR, radiation pattern have been calculated. It is found that antenna resonates at 2.95 GHz and 6.01 GHz for lower and upper resonance frequencies respectively. The bandwidth of the L-strip fed slot loaded compact rectangular microstrip patch antenna at lower resonance frequency is 1.16% (simulated) and 10.16% (theoretical) whereas at upper resonance frequency, it is 1.5% (simulated) and 2.51% (theoretical). The characteristics of the L-strip fed slot loaded compact rectangular microstrip patch antennas is compared with other rectangular patch antennas. Circuit diagram of this antenna is proposed, fabricated and simulated using AWR circuit simulator. The theoretical results are compared with IE3D and AWR simulation results along with measured results and they are in close agreement.
