Abstract

This research introduces an optimization design of an ultra-wideband (UWB) half-circular planar antenna using genetic algorithm. The optimization process is conducted using an Application Programming Interface (API) links two softwares; MATLAB environment and ANSYS HFSS software. The UWB antenna design includes a semi-circular patch element, the UWB behavior is obtained using truncated ground plane incorporating a rectangular slot cut out of the ground. Genetic algorithm is exploited to optimize the length of partial ground plane and the size and position of the rectangular slot. The overall size of the antenna is 28×29×1.6 mm 3. Using the proposed fitness function, the ultra-wide band antenna configuration achieves an extensive impedance bandwidth spanning approximately 14.76 GHz (139.38%), covering frequencies from 3.21 GHz to 17.97 GHz for reflection loss S11 less than-10dB. The findings also indicate that the antenna exhibits a favorable peak gain of 3.7-6.24 dB in the desired band. Therefore, the proposed methodology proofs to be effective to acquire the best UWB behavior of the antenna.
