ABSTRACT:
An antenna device for a direction finder includes a substantially grounded conductive base plate, a plurality of web-shaped antenna elements mounted in spaced relation on the base plate and having central portions extending in crisscross relation and insulated from each other, an electronic switching circuit for alternately grounding ends of the antenna elements and picking up reception outputs from opposite ends of the antenna elements at a constant period with the antenna elements being switched out of phase at an angle corresponding to the angle at which the antenna elements extend across each other, and a circuit for combining outputs from the antenna elements. According to another embodiment, the antenna elements comprise the web-shaped antenna elements and a vertical antenna element disposed substantially centrally in the web-shaped antenna elements.
