Abstract: front page image
(EN)An antennal device which is of small-sized planar construction, superior in productivity, and capable of forming a main beam tilted from vertical direction to horizontal direction. In this antenna device, an antenna (105) composed of two slot elements (109a, 109b) formed on the surface of a substrate (108) by cutting a copper foil and disposed in parallel, and microstrip lines (110a, 110b) formed of copper foil on the back of the substrate (108) are disposed on the inside bottom surface of a mirror case (103) at a distance (h) spaced from a mirror (104) made of metallic material. The slot elements (109a, 109b) are excited in that a phase difference is produced by microstrip lines (110a, 110b) constituting a T-branch circuit, so as to form a beam tilted from vertical direction to surface direction with respect to the substrate (108) surface under the influence of the mirror (104) operating as a reflecting plate.
(FR)Un dispositif d’antenne qui est une petite construction planaire, de productivité supérieure, et susceptible de former un faisceau principal incliné de la direction verticale vers la direction horizontale. Dans ce dispositif d’antenne, une antenne (105) composée de deux fentes (109a, 109b) formées sur la surface d’un substrat (108) en découpant une feuille de cuivre et disposées en parallèle, et des lignes de microruban (110a, 110b) formées de feuille de cuivre sur l’arrière du substrat (108) sont disposées sur la surface inférieure interne d’un étui à miroir (103) à une distance (h) d’un miroir (104) fabriqué à partir d’un matériau métallique. Les fentes (109a, 109b) sont excitées du fait qu’un déphasage est généré par les lignes de microruban (110a, 110b) formant un circuit en T, de sorte à former un faisceau incliné de la direction verticale vers la direction de la surface par rapport au substrat (108) sous l’influence du miroir (104) fonctionnant comme une plaque réfléchissante.
(JA) 小型な平面構造で、かつ生産性に優れ、鉛直方向から水平方向にチルトした主ビームを形成することのできるアンテナ装置。この装置では、基板(108)の表面に銅箔を切削して形成され、平行に配置された2つのスロット素子(109a)及び(109b)と、基板(108)の裏面に銅箔で形成されたマイクロストリップライン(110a)及び(110b)から構成されたアンテナ(105)を、金属材料で形成されたミラー(104)から間隔hを隔ててミラーケース(103)内部の底面に配置する。スロット素子(109a)及び(109b)は、T分岐回路を構成するマイクロストリップライン(110a)及び(110b)により位相差が生じて励振され、反射板として動作するミラー(104)の影響で基板(108)面の垂直方向から面方向へチルトしたビームが形成される。
