Title:
ANTENNA FOR FORMING TWO BEAMS, AND HYBRID ANTENNA COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/166018
Kind Code:
A1
Abstract:
The present application relates to an antenna for forming two beams. The antenna comprises: an oscillator array, which comprises first and second oscillator groups, wherein the first and second oscillator groups each comprise at least three first oscillators; and a feed network, which comprises first and second feed networks that are independent of each other, wherein the first feed network comprises a first power divider and first cable sets, the first power divider being electrically connected to each first oscillator by means of a corresponding first cable set, and the first power divider and/or the first cable set is used for adjusting the phase of a signal, which is used for forming a first beam, in each of the first oscillators; and the second feed network comprises a second power divider and a second cable set, the second power divider being electrically connected to each second oscillator by means of a corresponding second cable set, and the second power divider and/or the second cable set being used for adjusting the phase of a signal, which is used for forming a second beam, in each second oscillator. By means of the present application, the co-polarization isolation effect of dual-beam signals is better, and the beam directivity is more stable.
