Improvements relating to antennas |
摘要 |
An antenna comprises a single loop 10 having opposed gaps 12, 14. The antenna can be formed by etching copper on a PCB. In another embodiment (Fig. 6), two such loops are arranged orthogonally and by switching across one of the gaps (Fig. 10) the antenna can be operated selectively in horizontal linear polarisation or in circular polarisation. |
