BALANCED ANTENNA

摘要

A balance antenna capable of directly receiving an unbalanced signal includes a pair of radiating units symmetrical with respect to a symmetrical axis. Each radiating unit includes a high-frequency radiating part and a low-frequency radiating part. The high-frequency radiating part includes a frame, a feed-in arm extending from the frame and parallel to the symmetrical axis and having a feed-in point at a distal end thereof, and an enhancing arm extending from the frame and incline relative to the feed-in arm. The low-frequency radiating part extends from the frame and partially around the high-frequency radiating part, and is bent toward the feed-in arm. The low-frequency radiating part has a distal free end close to the feed-in point.

1. A balanced antenna capable of directly receiving an unbalanced signal, said balanced antenna comprising a pair of radiating units that are symmetrical with respect to a symmetrical axis, each of said radiating units includes:
a high-frequency radiating part including a frame that has a junction point and a coupling point opposite to each other, a feed-in arm that extends from said junction point away from said frame and parallel to the symmetrical axis and that has a feed-in point at a distal end thereof, and an enhancing arm that extends from said junction point away from said frame and that is inclined relative to said feed-in arm; and a low-frequency radiating part extending from said coupling point away from said frame and partially around said high-frequency radiating part, being bent toward said feed-in arm, and having a distal free end close to said feed-in point.
