Abstract
An antenna system for electromagnetic compliance testing within a frequency range includes a driven element mounted on a boom and including opposed first and second length-adjustable conductors. A length-adjustable passive element is mounted on the boom and spaced apart from the driven element and including opposed third and fourth length-adjustable conductors. An RF input connector is coupled between a feed path to a feed end of each length-adjustable conductors in the driven element. The feed path is configured to minimize stray reactances and stub effects within the frequency range.
