Title (EN) BROADBAND ANTENNA DEVICE
(FR) DISPOSITIF D’ANTENNE HAUT DÉBIT
(JA) 広帯域アンテナ装置
Abstract:
(EN) A thin broadband antenna device enabling a reduction in the size of a radiating element even when a dielectric substance is not used. The broadband antenna device (10) comprises a gland plate (12) and the flat-shaped radiating element (14) installed on the same plane (x, y) as a plane on which the gland plate extends. The radiating element (14) is formed in an elliptic shape. The radiating element (14) is separated by a prescribed feeding distance &Dgr;FD from the gland plate (12). The ratio of the outer diameter 2aout of the elliptic shape in x-direction to the outer diameter 2bout of the elliptic shape in y-direction is 8:5. The elliptic radiating element (14) comprises an elliptic opening (14a) formed concentric with the elliptic shape having a center (O). The inner diameter 2bin of the elliptic opening (14a) of the elliptic shape in the y-direction is half the outer diameter 2bout of the elliptic shape in the y-direction. The inner diameter 2ain of the elliptic opening (14a) of the elliptic shape in x-direction is desirably half the outer diameter 2aout of the elliptic shape in x-direction or smaller.
(FR) L’invention concerne un dispositif d’antenne mince haut débit permettant de réduire la taille d‘un élément irradiant même si l’on n’utilise pas de substance diélectrique. Le dispositif d’antenne haut débit (10) comprend une plaque de garniture (12) et l’élément irradiant de forme plate (14) installé sur le même plan (x, y) comme plan sur lequel s’étend la plaque de garniture. L’élément irradiant (14) est de forme elliptique. L’élément irradiant (14) est séparé d’une distance d’avance prescrite &Dgr;FD de la plaque de garniture (12). Le rapport du diamètre externe 2aout de forme elliptique dans la direction x jusqu’au diamètre externe 2bout de forme elliptique dans la direction y est 8:5. L’élément irradiant elliptique (14) comprend une ouverture elliptique (14a) concentrique avec la forme elliptique ayant un centre (O). Le diamètre interne 2bin de l’ouverture elliptique (14a) de forme elliptique dans la direction y correspond à la moitié du diamètre externe 2bout de forme elliptique dans la direction y. Le diamètre interne 2ain de l’ouverture elliptique (14a) de forme elliptique dans la direction x correspond idéalement à la moitié du diamètre externe 2aout de la forme elliptique dans la direction x, voire moins.
(JA)  誘電体を用いない場合でも、放射素子の小型化が可能な薄型の広帯域アンテナ装置を提供すること。  グランド板12と、このグランド板が延在する面と同一平面(x、y)上に設けられた扁平形状の放射素子14とを有する広帯域アンテナ装置10において、放射素子14が楕円形をしている。放射素子14とグランド板12との間が所定の給電間隔ΔFDだけ離間している。楕円形のx方向の外径2aoutと楕円形のy方向の外径2boutとの比は、8:5である。楕円形の放射素子14は、当該楕円形と同心Oの楕円開口14aを持つ。楕円形のy方向における楕円開口14aの内径2binは、楕円形のy方向の外径2boutの半分である。楕円形のx方向における楕円開口14aの内径2ainは、楕円形のx方向の外径2aoutの半分以下であることが望ましい。
