High-performance dual-polarized radiating element and isolation adjustment method

Abstract

The invention provides a high-performance dual-polarized radiating element, which comprises a radiation patch component, a first feed balun, a second feed balun and a power divider plate, wherein thefirst feed balun and the second feed balun are orthogonally arranged on the power divider plate; the radiation patch component is located at the upper parts of the first feed balun and the second feedbalun and comprises radiation patches and a medium carrier; the radiation patches are located at the front side of the medium carrier; and a pattern choke and coupling branches are arranged at the back side of the medium carrier. The performance of the radiating element is effectively improved through the pattern choke and the coupling branches, so that the high-performance dual-polarized radiating element has the characteristics of being wide in band, high in gain, good in polarization characteristic, good in isolation characteristic and small in boundary influence. Accordingly, the invention further discloses an isolation adjustment method for the dual-polarized radiating element. The polarization isolation is effectively improved through arranging decoupling devices at the lower partsof the radiation patches. The high-performance dual-polarized radiating element is suitable for array forming application of single array element or multi-array antennas, and especially suitable for array forming application of large-scale dense array antennas with medium and strong coupling boundaries for 5G communication.
