| Popis: |
A new high-gain cylindrical dielectric resonator antenna (DRA) with a large bandwidth is proposed. A cylindrical dielectric resonator (DR), a double-annular patch and a metallic cylinder are used to obtain a large bandwidth and a high gain. The mode TM12 excited in the patch is used to enhance the gain of the DRA, and the cavity formed by the metallic cylinder provides a further higher gain and a larger bandwidth. The results demonstrate that the proposed DRA achieves a large bandwidth of 23% from 5.4 to 6.8 GHz with VSWR less than two and a high gain around 12 dBi. |
