摘要：
In this paper, a rectangular slotted waveguide array is proposed for high power microwave applications. The antenna has been designed in the context of implementing a non-lethal high power transmission device onboard a drone to stop and neutralize non-cooperative vehicles. The proposed antenna comprises 16 slotted waveguides and a beamforming network, which is folded to maximize the compactness of the antenna. It has been specifically designed to send maximum EM energy in the range 20 degrees-30 degrees off-axis direction to avoid undesired ground reflections during operations. It has the ability to withstand a peak power of 500 kW. A measured gain of 27.7 dBi has been obtained at 3.15 GHz. The antenna has been successfully used to stop a car engine from a distance of approximately 9 meters.
