Comparative Analysis of Stack Shaped Microstrip Patch Antenna

A compact stack antenna consisting of square patch, loop couplers and inset feed line is simulated in this paper. The proposed antenna have a stacked patch antenna with an arrangement of two substrates separated by an air gape, A coupling is provided using square loop structure. The simulation results obtained with stacked structure are discussed and comparative analysis of these parameters with reference antenna is done in this paper. Simulation results obtained for return loss, polar radiation and pattern voltage standing wave ratio (VSWR) shows its suitability for ultra wide band application.
