Design and analysis of proximity microstrip patch antenna with parasitic lines

The design presented here mainly focuses on implementation of a single feed compact rectangular microstrip patch antenna (MSA) for single band application. The antenna presented here also works in dual band but its best performance has been obtained when optimized to work in single band mode. In this paper, a new feeding structure is applied in the patch antenna design to overcome undesirable features of the earlier multilayer feeding structures while maintaining their interesting features. To make the proposed antenna more efficient the optimization of the antenna design parameters have been done using HFSS's optometric. For the proposed antenna the resonant frequency has been obtained at 6.03GHz, 9.60GHz, 11.62GHz, return loss of -43.30, -37.68,-11.89db with Bandwidth of 165MHz, 271MHz, 300MHz respectively. The characteristics of the designed structure are investigated by using FEM based electromagnetic solver.
