A Novel Optimization Technique for a Stacked Patch Antenna

In this paper a novel optimization technique for a stacked antenna is presented. The stacked patch antenna consists of two layers of E-shaped patches. The optimization strategy for this E-shaped stacked patch antenna is based on Genetic Algorithm. In the proposed strategy, optimization is done in a recursive manner. The optimized antenna exhibits a cross-pol maximum atleast 16dB below the co-pol maximum with -13.5dB returnloss at 2.4GHz. The antenna exhibits an impedance bandwidth of around 10%. The proposed antenna can be used for wireless communication applications in 802.11b band. The optimization is performed in MATLAB and the simulations are verified in Microwave Office.
