Analysis of Proximity Coupled Microstrip Patch Antenna for Wireless Applications

In this article, an analysis of dual band proximity couple stacked microstrip patch antenna has been proposed. The theoretical investigations of antenna parameters such as return loss, gain and radiation pattern are calculated. It is found that antenna resonate at two distinct modes at lower and upper resonance frequencies, i.e. TM01 and TM02. The bandwidths of the proposed antenna are compared with simulated and theoretical results. The frequency ratio is also compared for upper to lower resonance frequencies with theoretical and simulated results. The theoretical results are compared with IE3D simulation results and they are in close agreement.
