Ultra‐wideband magnetoelectric antenna with dual polarization and compact size

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 (0.87λ0) × 95 mm (0.87λ0) × 65 mm (0.6λ0). 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.

A broadband transparent antenna applied in indoor mobile communication system

“…1,2 With the advent of the 5G era, there are many available frequency bands for mobile communication systems, such as GSM380, CDMA850, GSM900, DCS1800, PCS190, UMTS, LTE2300, LTE2500, and N78, which require antennas to have broadband characteristics. 3 Therefore, a broadband transparent antenna with a simple structure and stable performance applied to indoor mobile communication will have a wide application prospect.…”
