چکیده :

This paper proposes a novel wideband dual-polarized base-station antenna. The proposed antenna consists of four slotted diamond-shaped patches and two coaxial feed lines. Additionally, the antenna is backed by a box-shaped reflector that is employed to ensure a more stable radiation characteristics over the operating bandwidth. Simulated result demonstrates a wideband impedance bandwidth of 93% (1.68-4.60 GHz, 2.92 GHz) with high matching performances. Having wider bandwidth while maintaining a stable far-field characteristics over this considerably capacious bandwidth provides the antenna with the ability to cover multiple frequency bands that exist within sub-6 GHz frequency spectrum. Details of the characteristic mode analysis (CMA) design procedure, simulated and measured gain and radiation pattern characteristics will be presented at the conference.
