Dual polarised antenna with high isolation for small base‐station applications is proposed. The proposed antenna is composed of two metallic trapezoidal dipole elements, two metallic feed plates, a dielectric substrate, a metallic cube and a radome. The measured −10 dB impedance bandwidth is 2.4 GHz to 2.8 GHz in Port‐1 and 2.5 GHz to 3 GHz in Port‐2. The proposed antenna has an isolation of >45 dB at the centre frequency. The measured average antenna gain is 7.5 dBi, and the cross polarisations are all <30 dB below the co‐polarisation value.
