Dual-polarized patch antenna for wireless communication

The design of a dual-polarized patch antenna for Ku-band is presented in this paper. The cornerchopped square patch with bent slots is adopted in this design. The antenna has a compact structure and the total size is 15 × 15mm2. The result shows that the impedance bandwidth (VSWR ≤ 2) of the proposed antenna is 7.72% (from 11.8GHz – 12.75GHz). The antenna has achieved a stable radiation performance with gain greater than 4.25dBi across the whole operating frequency (11–14GHz). Details of the proposed antenna design and results are presented and discussed. The patch shows a high matching level in Ku-band and isolation elements that make it a suitable radiating element for base station in the wireless communication.
