Radar sensor antenna with anti-reflection element

摘要

An antenna (10) for a radar sensor includes an emitter element (18), a receiver element (32), and an anti-reflection element (34). The emitter element (18) is configured to direct the emitted signal (20) along a boresight (22) that intersects a fascia (12). The receiver element (32) is configured to detect a reflected signal (26) reflected by an object located beyond the fascia (12). The anti-reflection element (34) is configured to reduce reflection by the antenna (10) of an early-reflection portion (30) reflected by the fascia (12).
