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 mm 3 or ∼0.191 λ 0 × 0.384 λ 0 × 0.032 λ 0 at 4.8 GHz.
