Analysis of Multilayer Rectangular Patch Antenna for Broadband Operation.

In this paper analysis of multilayer patch antenna has been carriedout. The antenna shows the broad bandwidth when a patch is stacked over fed patch in gap coupled structure. Typically a 42.65% bandwidth is achieved in three layer antenna. Further the bandwidth of the antenna depends inversely on the gap(s). The gain of the antenna is found to be 6.08 dB with 3 dB beam width of 92°. The theoretical results are compared with IE3D simulation and reported experimental data. [ABSTRACT FROM AUTHOR]
