Title:
BROADBAND INTEGRATED BALANCED-TO-UNBALANCED CONVERTER AND ANTENNA UNIT
Document Type and Number:
WIPO Patent Application WO/2021/073089
Kind Code:
A1
Abstract:
Disclosed are a broadband integrated balanced-to-unbalanced converter and antenna unit; the broadband integrated balanced-to-unbalanced converter comprises a dielectric substrate, a microstrip line, and metal strips; said microstrip line is arranged on one side of said dielectric substrate, and said metal strips are arranged on the other side of the dielectric substrate; the metal strips are a first metal strip and a second metal strip arranged coplanarly; there is an isolation gap between the first metal strip and the second metal strip; tooth-shaped gaps are provided on each side of the first metal strip and the second metal strip, forming the isolation gap. The line unit of the present invention can achieve 2/3/4/5G frequency band (1.7-3.6 GHz) ±45° dual-polarization stable electromagnetic radiation, and has the features of a wide operating frequency band, high isolation, and a stable radiation pattern.
