ANTENNA FOR MOBILE-COMMUNICATION BASE STATION

摘要

The present invention relates to an antenna for a mobile-communication base station and includes a reflective plate, and a first radiant element having a first frequency band formed on the reflective plate, wherein the first radiant element includes: a slot structure that is formed as a letter “X” hole directly in the entire reflective plate and generates a transmission signal having X-shaped dual polarizations that are orthogonal to each other, and a metallic patch plate that is installed on the top of the slot structure so as to be insulated from the reflective plate.

1. An antenna for a mobile communication base station, the antenna comprising:
a reflective plate; and a first radiant element of a first frequency band, which is formed on the reflective plate, wherein the first radiant element comprises:
a slot structure which is directly formed in the reflective plate in the form of an overall X-shaped hole to generate a transmission signal having X-shaped dual polarizations that are orthogonal to each other; and a patch plate formed of a metallic material on a top surface of the slot structure in such a way to be insulated from the reflective plate.
