- Abstract
A unidirectional dual‐polarised antenna is presented, by applying a cavity‐backed annular slot and two mutually perpendicular microstrip feed lines. To improve the isolation between two ports of the designed antenna, a pair of conductor strips is introduced at the opposite side of the feed lines and a metal cylinder into the cavity centre. Aimed at 2.4 GHz wireless local area network systems, a prototype antenna has been fabricated based on the FR4 substrate. The measured results show that an isolation value of over 33 dB can be attained and the co‐polarised level is 30 dB larger than the cross‐polarised in the main radiation direction. In addition to compact structure, the operating band with about 5 dBi antenna gain indicates the proposed antenna is suitable for indoor multiple‐input–multiple‐output (MIMO) base station systems.
