Abstract
A new wideband low-profile omni-directional dielectric resonator antenna (DRA) is presented. By joining back-to-back two thin identical rectangular high-permittivity dielectric resonators (DRs) and feeding the arrangement with a microstrip feed line inserted in-between the DRs, an impedance bandwidth covering the frequency range from 4.78 to 12.32 GHz, or ~88.2%, is achieved. Importantly, the measured results show that the proposed low-profile DRA also provides a stable omni-directional radiation pattern with low cross-polarisation. The proposed antenna size is 12 × 24 × 2 mm3 or ~0.191λ0 × 0.384λ0 × 0.032λ0 at 4.8 GHz.
