ABSTRACT:
This invention relates to a microwave antenna regulating device for an automatic door, in which an antenna of a microwave radar automatic door sensor is mounted on a rotating disk of a regulating device which can adjust the detecting direction on a base in leftward and rightward directions. The rotating disk is provided with holding means for further adjusting the detecting direction of the antenna in backward and forward directions. Therefore, the regulating device can adjust the microwave antenna in backward-forward and leftward-rightward directions whereby when the microwave radar sensor is used in the actuating switch of an automatic door, the detecting range can be arbitrarily adjusted by adjusting the direction of the antenna according to the environmental condition to make the opening or closing of the automatic door more active and optimize the function of the automatic door.
