Abstract :
In this article, the analysis of dualband L-strip fed compact semi-circular disk microstrip patch antenna has been presented using circuit theory concept. The antenna parameters such as return loss, VSWR and radiation pattern are calculated. The effect of geometric dimensions of the proposed antenna such as length of vertical and horizontal portion of L-strip is investigated. It is found that antenna resonate at two distinct modes i.e. 1.3 GHz and 6.13 GHz for lower and upper resonance frequencies respectively. The bandwidth of the proposed antenna at lower resonance frequency is 6.61% (simulated) and 10.64% (theoretical) whereas at upper resonance frequency, it is 6.02% (simulated) and 9.06 % (theoretical). The theoretical results are compared with IE3D simulation results as well as experimental results and they are in close agreement.
