Horizontal polarization omnidirectional antenna

摘要

PROBLEM TO BE SOLVED: To make a horizontal polarization omnidirectional antenna compact.;SOLUTION: A horizontal polarization omnidirectional antenna 1 comprises an antenna part 3 having a single polyhedron 36 consisting of a plurality of antenna surfaces 41 arranged multilaterally. Grooves 42a-42d constituting third output waveguides 33a-33d are formed, respectively, in each antenna surface 41 of the polyhedron 36, and walls 43a-43d constituting third output waveguides 33a-33d by covering the openings thereof are provided in the grooves 42a-42d. In the walls 43a-43d, slots 44a-44d communicating with the third output waveguides 33a-33d and radiating horizontal polarization in a predetermined frequency band are formed.;COPYRIGHT: (C)2014,JPO&INPIT
