Title:
WIDE-ANGLE SCANNING DUAL-POLARIZED DIPOLE ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/228759
Kind Code:
A1
Abstract:
The present invention relates to the technical field of antennas. Disclosed is a wide-angle scanning dual-polarized dipole antenna, comprising a first metal arm, an antenna support column, a second metal arm, and a feed balun. The first metal arm is located on the top of the antenna and is configured to improve the impedance fluctuation of the antenna during scanning at a large angle. The feed balun is located at the bottom of the antenna and is configured to convert an unbalanced feed input by a coaxial wire into a balanced feed. The present invention greatly improves the impedance matching of the antenna during large-angle scanning, and effectively improves the performance of the antenna during wide-angle scanning. In addition, the antenna has a good cross-polarization performance. Finally, the snows and rains can hardly be accumulated on the metal dipole arm and the top metal arms because the cross-sections of both arms are small due to their longitudinal blade-shaped bending structures, so that the influence of snow and rain on the performance and service life of the antenna is greatly reduced, and the antenna can be applied even in severe weather conditions such as heavy rain and heavy snow.
