摘要
We propose a circularly polarized cavity-bocked slot (CBS) antenna which is composed of two symmetrically placed L-shaped slots on a 150 X 100 mm(2) ground plane (back side) and fed by a microstrip network on the opposite plane (front side). A metal cavity is placed at the back side to reduce the effect caused by the wall behind the antenna and enhance the radiation on the front side; in this way it is suitable to be "buried-on-wall." Simulation results of the return loss, radiation patterns, axial ratios, and gain are presented. The antenna was fabricated on FR-4 substrate and the measured return loss agrees well with the simulated one.
