一种新型Ku频段宽带高增益双极化微带天线阵列
A novel dual-polarization microstrip antenna array with wideband and high gain in Ku band
摘要
Abstract
In this paper, a novel design of dual-polarized microstrip patch element and 96-element array with wide bandwidth and high gain is proposed for Ku band application. A stacked patch antenna (SPA) architecture is adopted in the element design in order to increase the bandwidth and gain. Dualqayered feeding technique is used to achieve the dual-polarization, where the horizontal polarization port is fed with a coplanar microstrip line, while the vertical polarization port is excited by a probe. The anti-phase feeding technique is considered in design of the feeding net- work, which leads to lower cross polarization. The simulated and experimental resuits show that the gain of the array with 96-element reaches 26 dBi with an aperture efficiency of 51%, the cross-polarization is lower than -30 dB. In addition, the relative impedance bandwidths of the horizontal and vertical polarization ports are 11.3% and 13.7% , respectively, and the isolation between the dual polarization ports is better than 40dB.关键词
