Abstract

A 28-GHz endfire (modified Vivaldi) active antenna is described that contains a secondary, circularly polarized patch antenna for reception of an external injection-locking signal. Three of these devices are used to characterize an octagonal cylindrical reflector designed for creating an omni-directional transmitter suitable for use in point-to-multipoint communication systems. The experiments provide data that validates the approach used to simulate the azimuthal radiation patterns. These simulations are then extended to predict the patterns from a full eight-element array
