本文介绍了一种能够产生圆极化和线极化传播的宽带极化可重构贴片天线。该天线由贴片、接地层和交叉馈电探针组成，交叉馈电探针由p-i-n二极管重新配置。所提出的交叉探针结构有助于天线的宽阻抗带宽特性。通过控制p-i-n二极管的操作，可以激发贴片的不同极化。该天线具有左旋圆极化、右旋圆极化和线极化三种工作模式。对于CP模式，天线产生19.2%的轴比（AR）带宽（对于AR
In this letter, a wideband polarization-reconfigurable patch antenna with capability of generating circular polarization (CP) and linear polarization (LP) propagations is introduced. This antenna consists of a patch, a ground plane, and a cross-feeding probe, which is reconfigured by p-i-n diodes. The proposed cross-probe structure contributes a wide impedance bandwidth feature for the antenna. By controlling the operation of the p-i-n diodes, different polarizations of the patch can be excited. This antenna has three selective operating modes, including left-hand circular polarization, right-hand circular polarization, and linear polarization. For CP modes, the antenna yields an axial-ratio (AR) bandwidth of 19.2% (for AR
