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 TM 12 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 measured results demonstrate that the proposed DRA achieves a large bandwidth of 23% from 5.3 to 6.8GHz with VSWR less than two and a high gain around 11 dBi.
