Abstract: A dual polarised planar antenna (10) comprising first (12) and second (13) antenna elements having respective orthogonal polarisations, the antenna elements (12, 13) being arranged in a back-to-back configuration and fed directly by respective first and second antenna feeds (15), wherein the dual polarised planar antenna (10) further comprises a parasitic element (14) arranged between the antenna elements (12, 13) such that in-use the antenna feeds (15) are decoupled. Particularly suited to low profile antennas and compact antenna base stations. Also relates to a method of manufacture.
