摘要：

A wide bandwidth and wide beamwidth L-probe-fed patch antenna array with a novel design of grounded structure is proposed and tested. The antenna is made of stacked patches supported by plastic screws. The patches are proximity fed via L-shaped probe. By cutting slots in two vertical side walls of a box-shaped grounded structure, an impedance bandwidth larger than 20% (SWR < 1.5), an H-plane beamwidth over 90 degrees, and much reduction in backlobe radiation can be obtained. Details of the proposed antenna, simulation, and experimental results are presented and discussed.
