Summary:The increasing demand for ultra-wideband (UWB) communication systems necessitates compact, high-performance antenna arrays with efficient polarization and impedance characteristics.This paper presents the design and analysis of a 2×2 circularly polarized microstrip patch antenna array optimized for operation at 8.25 GHz, a key frequency within the ultra-wideband (UWB) spectrum. The design incorporates a Wilkinson power divider for uniform power distribution and an aperture-coupling mechanism to enhance impedance matching and minimize back radiation. Simulated results demonstrate low return loss, high polarization purity, and stable gain, making the proposed antenna suitable for high-performance wireless communication and radar applications within its operational bandwidth.
