Title:
MULTI-BAND BASE STATION ANTENNA HAVING IMPROVED ISOLATION CHARACTERISTICS
Document Type and Number:
WIPO Patent Application WO/2022/131648
Kind Code:
A1
Abstract:
Disclosed is a multi-band base station antenna having improved isolation characteristics. The antenna disclosed herein comprises: a reflector; a plurality of high-band radiators arranged on the reflector; and a plurality of low-band radiators arranged on the reflector. Each of the plurality of low-band radiators comprises: a radiation substrate; a first dipole radiator including a first + dipole arm and a first - dipole arm formed on the radiation substrate; a second dipole radiator including a second + dipole arm and a second - dipole arm formed on the radiation substrate; and a metal coupler coupled to the lower portion of the radiation substrate. The metal coupler comprises: a first coupling patch located below the first + dipole arm; a second coupling patch located below the first - dipole arm; a third coupling patch located below the second + dipole arm; and a fourth coupling patch located below the second - dipole arm. According to the antenna disclosed herein, there is an advantage in that a good degree of isolation can be achieved between the low-band radiators and the high-band radiators, and stable standing wave ratio characteristics can be secured.
