FEEDING WAVEGUIDE AND SECTOR ANTENNA

摘要

A sector antenna provided with a feeding waveguide leading from a feeding port to a plurality of antennas while being branched at a portion. The feeding waveguide comprises a waveguide and has a main feeder line extending from a waveguide which extends from the feeding port while being branched in two directions, and a branch feeder line branched from the opposite ends of the feeder line in two directions, respectively. At a position of the branch feeder line where each branch waveguide is branched to extend from the main feeder line, a sector selection mechanism for flocking each branch waveguide selectively by forming a conductor wall for closing the cross-section of each branch waveguide effectively is provided.
