摘要：

In this communication design and performance of a novel single-layer assembly of gap coupled elements in elliptical shape is proposed to achieve broadband performance with circular polarization. Out of five patches considered in this assembly, two pairs of patches having different patch areas are arranged close to an edge truncated elliptical patch. The central edge truncated elliptical patch is fed through inset feed arrangement and the other patches are parasitically gap coupled to the central patch. With such an arrangement, an improved impedance bandwidth of 1.58 GHz or 18.5% with respect to central frequency 8.5 GHz is achieved. Three resonant modes are excited with this arrangement giving improved bandwidth and gain in comparison to a conventional elliptical patch antenna with same semi-major and semi-minor axes. In the entire bandwidth, the simulated radiation patterns of proposed arrangement of patches are more or less identical in shape.
