通过嵌入短通孔，提出了一种双正交极化的宽带双频l探针耦合贴片天线阵列。该阵列实现了0.82-0.96GHz和1.71-2.17GHz两个较宽的工作频段，回波损耗小于-14dB。在两个通带之间，测量到两个极化之间的高隔离度超过30dB。此外，该阵列提供灵活的频率比和稳定的辐射方向图。由于其宽带宽和高性能，所提出的天线阵列非常适合用于几乎所有现代无线通信应用的基站天线，包括CDMA， GSM， PHS， DCS和UMTS。
By embedding shorting vias, a wideband dual-frequency L-probe coupled patch antenna array with dual orthogonal polarization is presented. This array achieves two broad operating bands, which cover 0.82-0.96GHz and 1.71-2.17GHz, with a return loss less than -14dB. Across both passbands, a high isolation of more than 30dB is measured between two polarizations. Besides, this array provides flexible frequency ratio and stable radiation patterns. Due to its wide bandwidth and high performance, the proposed antenna array is highly suitable for base station antenna for almost all modern wireless communication applications, including CDMA, GSM, PHS, DCS and UMTS.
