Summary:
In this paper, we propose a novel type of polarization diversity antenna construction for mobile wireless terminal. This diversity antenna construction is composed of a 180? hybrid and two antenna elements. By changing the relative excitation phase between two antenna elements arranged on both sides of the conducting-plate to in-phase or out-of-phase, the current on the antenna elements and on the conducting-plate is changed. In the above-mentioned method, the proposed antenna can obtain two polarization-modes. Additionally, the correlation coeffcient of the radiation pattern between the two modes is very low.
