Abstract

Abstract: Design of ultra‐wideband (UWB) dual‐polarized magnetoelectric (ME) dipole antenna with compact size is presented. The proposed antenna consists of a double‐layer ME dipole, a pair of cross‐placed Γ‐shaped probes, and a box‐shaped reflector. Total size of the final design is 95 mm (0.87 λ 0 ) × 95 mm (0.87 λ 0 ) × 65 mm (0.6 λ 0 ). Both simulated and measured results show that the proposed antenna has an operating bandwidth of 127.3% (1–4.5 GHz) with voltage standing‐wave ratio (VSWR) ≤ 2.2 and 5.1 dBic ≤ gain ≤ 9.6 dBic. A stable unidirectional radiation pattern is achieved over the whole band. The cross‐polarization level is less than −15 dB and isolation between two ports exceeds 15 dB. Due to its compact size and good performance, the proposed antenna can be a competitive candidate in most wireless communication application scenarios.
