Abstract :
A broadband dual-polarised antenna with four end-to-end folded dipoles and a U-shaped ground is presented. Stable and symmetric radiation patterns at slanted plusmn45deg polarisation have been obtained within the band 1.71-2.17 GHz. Measurements show two linear polarisations with an isolation of more than 30 dB over the operating frequency band. A return loss less than -14 dB is achieved and the measured cross-polar level is 23.5 dB below the co-polar level within the above-mentioned band.
