CIRCULARLY-POLARIZED DUAL-FREQUENCY ANTENNA
(FR)
ANTENNE À DOUBLE FRÉQUENCE À POLARISATION CIRCULAIRE
(ZH)
圆极化双频天线
Abstract:
(EN)
Disclosed in the embodiments of the present invention is a circularly-polarized dual-frequency antenna, comprising a feed network and a plurality of dipoles; the plurality of dipoles are provided on a cylindrical surface, and each of the dipoles comprises a first oscillator unit and a second oscillator unit, both the first oscillator unit and the second oscillator unit comprising a first oscillator and a second oscillator, the first oscillator comprising a first vertical portion and a first transverse portion, the second oscillator comprising a second vertical portion and a second transverse portion; the first vertical portion and the second vertical portion are parallel to the central axis of the cylindrical surface; the feed network is connected to the first oscillator units and the second oscillator units. In the embodiments of the present invention, the plurality of dipoles are provided on the cylindrical surface, such that the antenna has a better circular polarization performance. The design of the oscillator unit comprising a first oscillator and a second oscillator enables the antenna to have the capability to work at two frequencies.
(FR)
Les modes de réalisation de la présente invention concernent une antenne à double fréquence à polarisation circulaire, comprenant un réseau d'alimentation et une pluralité de dipôles, la pluralité de dipôles étant disposés sur une surface cylindrique et étant chacun pourvus de premier et second ensembles oscillateurs, les premier et second ensembles oscillateurs comprenant des premier et second oscillateurs, le premier oscillateur comportant une première partie verticale et une première partie transversale, et le second oscillateur comportant une seconde partie verticale et une seconde partie transversale, les première et seconde parties verticales étant parallèles à l'axe central de la surface cylindrique, et le réseau d'alimentation étant connecté aux premier et second ensembles oscillateurs. Dans les modes de réalisation de la présente invention, la pluralité de dipôles sont disposés sur la surface cylindrique, de telle sorte que l'antenne dispose d'une meilleure performance de polarisation circulaire. La conception de l'ensemble oscillateur comprenant des premier et second oscillateurs permet à l'antenne d'être apte de fonctionner à deux fréquences.
