Abstract
A microwave motion sensor including a patch antenna having a plurality of microwave radiating elements for transmitting and receiving a microwave signal where each microwave radiating element is of the antenna in an array configuration. A reflector is disposed above the antenna for downward shaping the radiating signal, where the microwave radiating elements together with the reflector provide a radiation pattern where a main beam is transmitted in a direction orthogonal to a surface of said antenna and a sided lobe transmitted downward in amplitude below the microwave motion sensor.
