    Abstract: 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).

    Abstract: A system and method for an electronically scanned antenna is provided in which phase shifters (204) are deposited en masse along with other electronically scanned antenna components on a wafer scale substrate (414) using a thin film process. Alternative wafer scale sizes may be utilized to furnish a required antenna aperture area. Significant processing costs for radar and communication systems are saved utilizing the present invention as compared with contemporary discrete phase shifters that are individually mounted on an antenna. In an aspect, the phase shifter (204) is made up of a base electrode (422), a barium strontanate titanate (BST) ferroelectric varactor (424) and a top electrode (426). The BST ferroelectric material (424) is a voltage variable dielectric, which generates a radiation phase. The radiation phase is regulated by a phase shifter control. The radiation phase generates an electromagnetic field about a radiating element (206) and electromagnetic radio waves are radiated from the radiating element (206).
