High gain omnidirectional land mobile base station antenna

Measurements and computations made on a 1.5-GHz 5.6-m (18.5-ft) aperture 2 degrees vertical beamwidth antenna with an omnidirectional horizontal pattern are presented. The gain is greater than 16 dBi over a range of 70 MHz. Good agreement between measured and computed patterns provides confidence that the elevation pattern can be used to predict the received field when the antenna is used in an urban multipath propagation environment.<
