本文提出了一种新的宽带双极化单微带贴片天线的设计，它具有高去耦输入端口和低交叉极化（XP）辐射。提出了一个原型的天线中心频率在1800 MHz。两种双线性极化都具有大于14%的10 dB回波损耗阻抗带宽，并且获得了两个输入端口之间的高去耦（S/sub 21/在整个带宽上小于-40 dB）。此外，在双线偏振的主平面中的XP辐射被认为小于-20 dB。
This paper presents a new design of a broad-band dual-polarized single microstrip patch antenna with highly decoupled input ports and low cross-polarization (XP) radiation. A prototype of the proposed antenna with center frequency at 1800 MHz is presented. Both the dual linear polarizations have 10-dB return-loss impedance bandwidths greater than 14% and high decoupling between the two input ports (S/sub 21/ less than -40 dB across the entire bandwidths) is obtained. Moreover, the XP radiation in the principal planes of the dual linear polarizations is seen to be less than -20 dB.
