Abstract :
We present a dual polarised multibeam antenna intended for use in a PCS (1850-1990 MHz) base station. Although the coupling between adjacent antenna columns is quite high the radiation patterns and cross-polar characteristics are satisfactory. The port-to-port isolation between polarisations is also limited by inter-array coupling but still exceeds 22 dB in the frequency band.
