英文摘要 | A novel technique is proposed for compact and dual-frequency design of single-feed rectangular micro strip antennas with a slit and rectangular slot placed at the patch center of top edge and closed the patch bottom edge, respectively. The two operating frequencies have orthogonal polarization planes, and have a low frequency ratio of about 1.13-1.20. The two resonant frequencies can also be much lower than the fundamental mode of a corresponding conventional patch antenna without the rectangular slot and slit. By properly selecting a rectangular slot and slit length in the proposed design, compact and dual-frequency characteristics can be obtained by feeding the patch at the same position. Details of the proposed antenna design and experimental results are presented and discussed. |
