Dual-polarized patch antenna for wireless communication

The design of a dual-polarized patch antenna for Ku-band is presented in this paper. The corner-chopped square patch with bent slots is adopted in this design. The antenna has a compact structure and the total size is 15 times 15 mm². The result shows that the impedance bandwidth (VSWR les 2) of the proposed antenna is 7.72% (from 11.8 GHz - 12.75 GHz). The antenna has achieved a stable radiation performance with gain greater than 4.25 dBi across the whole operating frequency (11-14 GHz). 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.
