摘要：
This paper proposes a periodic reconfigurable leaky wave antenna (LWA) that can realize fixed frequency dualpolarized beam scanning. The antenna operating frequency is 24.5-27.5GHz, consisting of a rectangular waveguide and 86 gapcoupled patch antennas, and the operating state of the patch antenna can be controlled by controlling the bias of the PIN diode. By controlling the diode switching states to control the unit length of the antenna, a steering beam with dual-polarized characteristic is achieved. Through CST simulation, this LWA can realize beam scanning of-14 degrees similar to 14 degrees at 25GHz.
