Beschreibung
Zusammenfassung:	An ultrasonic sensor having one side beam directivity is provided to increase the sensing range in a desired direction only by guiding ultrasonic wave, which is radiated from the front surface of an ultrasonic sensor, in a specific direction. An ultrasonic sensor having one side beam directivity includes an ultrasonic radiation port. The ultrasonic sensor is used in distance measurement, obstacle detection and obstacle evasion. The sensing region is restricted by blocking a part of the ultrasonic radiation port so that the ultrasonic wave is radiated in a specific direction.
