    摘要： In the sector antenna of the present invention, a feeder waveguide is formed that branches midway from a feeder port to each of a plurality of antennas. This feeder waveguide is formed from a waveguide tube and includes a main feeder line that extends from a waveguide that extends from the feeder port and branches in two directions, and branch feeder lines that each branch in two directions from the two ends of the main feeder line. Sector selection structures are provided for selectively shutting off each branch waveguide by effectively forming conductive walls for blocking the cross section of each of the branch waveguides at positions of each of the branch feeder lines that branch and extend from the main feeder line and from which each branch waveguide begins.

A dielectric substrate (1) has one surface connected to a top conductor (2) and an opposite surface connected to a bottom conductor (3). A pair of rows of via-holes connecting together the top conductor (2) and the bottom conductor (3) are formed along the signal transfer direction. A slit (6) is formed in a portion of the top conductor (2) overlying the central resonator among a plurality of resonators. The slit (6) extends in a direction perpendicular to the signal transfer direction. Slits (7, 8) are formed in each of portions of the top conductor (2) overlying resonators disposed at both ends.
