Abstract: 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.
