摘要

本文报道了一种具有方向图和极化分集的低姿态宽带天线。该天线由l板馈电差分驱动贴片天线和单极子天线组成。通过共享部分辐射元件，这两个天线被集成在一起。数值计算结果表明，该天线能在1.7 ~ 2.7 ghz频段内提供极化和方向分集，最低工作频率下天线总高度仅为0.11 λ0。此外，差分馈电方法保证了两种辐射方向图之间良好的隔离性和较低的包络相关系数，具有良好的分集性能。

A Low-profile Wideband Pattern and Polarization Diversity Antenna

In this paper a low-profile, broadband antenna with pattern and polarization diversity is reported. The antenna is composed of a L-plate feeding differentially driven patch antenna and a monopole antenna. By sharing part of the radiated element, these two antennas are integrated together. The numerical results show that the proposed antenna can provide a polarization and pattern diversity over the frequency band of 1.7-2.7GHz, and the overall height of the antenna is only 0.11 λ0 at its lowest operating frequency. Moreover, the method of the differential feeding ensures a good isolation and low envelope correlation coefficient between these two radiation patterns, which demonstrates an excellent diversity performance.
