ABSTRACT:
An antenna (100) includes overlapping conductive plates (102, 104) having a radiating end (112) and a feed end (114). The plates include partially overlapping edges (106) that flare away from each other as each edge progresses toward the radiating end (112). A dual conductor microstrip feed (110) is also provided. A transmission line (108) connects each plate to a different conductor (113, 115) of the microstrip feed. The transmission line comprises two substantially overlapping, parallel conductive ribbons (130, 131) that form an elbow (107) with a prescribed turn (109).
