Dual radiator monopole antenna

摘要

A dual radiator monopole antenna. An elongated low-band ground-coupled arm is disposed on a first surface of a printed circuit board. This arm is electrically connected to and spaced apart from a ground plane. An elongated high-band ground-coupled arm is disposed on a second surface of the printed circuit board, and like the low-band arm is electrically connected to and spaced apart from the ground plane. The high-band arm is oriented parallel to, and laterally displaced from, the low-hand ground-coupled ann. An elongated feed arm is disposed on the first surface of the printed circuit board, oriented parallel the ground-coupled arms and laterally displaced from them. A conductor in electrical feed connection with the feed arm extends from the feed arm across a portion of the ground plane.

1. A dual radiator monopole antenna comprising:
an elongated low-band ground-coupled arm disposed on a first surface of a printed circuit board, the elongated low-band ground-coupled arm (i) having a first end that is electrically connected to and extending from a ground plane, and (ii) being structured to be spaced apart from the ground plane along a portion of the elongated low-band ground-coupled arm; an elongated high-band ground-coupled arm disposed on a second surface of the printed circuit board, the elongated high-band ground-coupled arm (i) having a first end that is electrically connected to and extending from the ground plane, and (ii) being structured to be spaced apart from the ground plane along a portion of the elongated high-band ground-coupled arm; a feed arm disposed on the first surface of the printed circuit board, the feed arm (i) being electrically disconnected from the ground plane, and (ii) being structured to have a portion that is substantially parallel to the portion of the elongated low-band ground-coupled arm; and a conductor that is connected to the feed arm and extends from a connection point.
