Abstract

In this exploration, our focus lies on unveiling a novel Mixed Multi-Elliptical Shaped (MMES) microstrip patch antenna, notably compact in design. Using the co-planar waveguide (CPW) port technique on an FR-4 substrate, we introduce an antenna showcasing a dual fractional bandwidth, and it spans 76.95% from 2.87 to 6.5 GHz and 53.85% from 8.06 to 14 GHz. To enhance both Gain and Directivity, our design integrates a Hexagon Cell with an Octagon Slot array reflector. This addition results in a peak gain of 8.759 dBi and a maximum directivity of 9.537 dBi at 6 GHz. Achieving optimal Gain and Directivity involved precise adjustments to the gap between the antenna and the reflector plane. The overall dimensions of our proposed antenna measure 59×59×11.67 mm³. Rigorous simulations and empirical validation strongly support the potential of this antenna for applications in BT, WLAN, and WiMAX.
