A new half-power beam width (HPBW) base station (BS) antenna is described for use in 26 GHz- and 38 GHz-band point-to-multipoint (P-MP) fixed wireless access (FWA) systems which is narrower than the conventional design, and which efficiently meets the prescribed carrier-to-thermal noise power ratio (C/N) quality requirements. This development results in a reduction in antenna volume and the installation costs of the system. The validity of the new design in terms of C/N, carrier-to-interference signal power ratio (C/I) performance and the visibility of the propagation path are estimated.
