Dual function antenna structure and a portable radio having same |
摘要 |
A dual function antenna structure transceives in first and second modes. A first feed (120) feeds a primary antenna element (110) for operation in the first mode. A second feed (140) couples via a coupling element (130) to a portion of the first feed (120) or the primary antenna element (110) to realize a secondary antenna element. In a portable radio, dual function operation is thus possible by a compact structure by the first and second feeds (120, 140).
