Title (EN) NOVEL SPREAD SPECTRUM BROADBAND BASE STATION ANTENNA
(FR) ANTENNE INNOVANTE DE STATION DE BASE À LARGE BANDE À SPECTRE ÉTALÉ
(ZH) 一种新型扩频宽带基站天线
Abstract:
(EN) Disclosed is a novel spread spectrum broadband base station antenna, comprising a reflection plate, an antenna radiation element and a coupling element, wherein the antenna radiation element is fixed above the reflection plate by means of a support post; the coupling element is fixed above the antenna radiation element; the antenna radiation element comprises four radiating arms, a dielectric substrate and a feeder structure; two radiating arms form a +45-degree polarized oscillator and are fed by a first feeder, and the other two radiating arms form a -45-degree polarized oscillator and are fed by a second oscillator; the four radiating arms all comprise a diamond-shaped patch and a semi-circular patch printed on the dielectric substrate; the diamond-shaped patch is provided with a U-shaped gap; and the semi-circular patch is loaded at one corner of the diamond-shaped patch. The antenna has the advantages of a high bandwidth, a simple and novel structure, and a stable radiation pattern.
(FR) L’invention concerne une antenne innovante de station de base à large bande à spectre étalé, comprenant une plaque de réflexion, un élément de rayonnement d’antenne, et un élément coupleur, l’élément de rayonnement d’antenne étant fixé au-dessus de la plaque de réflexion au moyen d’un pilier de support ; l’élément coupleur étant fixé au-dessus de l’élément de rayonnement d’antenne ; l’élément de rayonnement d’antenne comprenant quatre bras rayonnants, un substrat diélectrique et une structure d’alimentation ; deux bras rayonnants formant un oscillateur polarisé à +45 degrés et étant alimentés par un premier dispositif d’alimentation, et les deux autres bras rayonnants formant un oscillateur polarisé à −45 degrés et étant alimentés par un deuxième oscillateur ; les quatre bras rayonnants comprenant tous une plaque rhomboïdale et une plaque semi-circulaire imprimées sur le substrat diélectrique ; la plaque rhomboïdale comportant un entrefer en forme de U ; et la plaque semi-circulaire étant chargée à un coin de la plaque rhomboïdale. L’antenne a les avantages d’une haute largeur de bande, d’une structure simple et innovante, et d’un motif de rayonnement stable.
