Abstract
(EN)
According to the present invention, the use of more frequency bands is enabled with fewer elements, and in particular, an antenna gain increases over a wide frequency range. Two antenna elements 21, 22 are erected on an antenna base 10. The antenna elements 21, 22 comprise: proximal end portions 21a, 22a; and two arm portions 211a, 211b, 221a, 221b extending in a strip shape in different directions away from the proximal end portions 21a, 22a. The inductance of at least one of the two arm portions 221a, 211b of the antenna element 21 is larger than the inductance of a planar conductor having the same material and substantially the same outer shape. The inductance of at least one of the two arm portions 221a, 221b of the antenna element 22 is larger than the inductance of a planar conductor having the same material and substantially the same outer shape.

La présente invention permet l'utilisation d'un plus grand nombre de bandes de fréquences avec moins d'éléments, et en particulier, un gain d'antenne augmente sur une large plage de fréquences. Deux éléments d'antenne 21, 22 sont déployés sur une base d'antenne 10. Les éléments d'antenne 21, 22 comprennent : des parties d'extrémité proximale 21a, 22a ; et deux parties de bras 211a, 211b, 221a, 221b s'étendant selon une forme de bande dans différentes directions à l'opposé des parties d'extrémité proximale 21a, 22a. L'inductance d'au moins l'une des deux parties de bras 221a, 211b de l'élément d'antenne 21 est plus grande que l'inductance d'un conducteur plan ayant le même matériau et sensiblement la même forme externe. L'inductance d'au moins l'une des deux parties de bras 221a, 221b de l'élément d'antenne 22 est plus grande que l'inductance d'un conducteur plan ayant le même matériau et sensiblement la même forme externe.

少ないエレメントでより多くの周波数帯の使用を可能とし、特に、広い周波数にわたってアンテナ利得を高くする。 アンテナベース10に、二つのアンテナエレメント21,22を立設させる。各アンテナエレメント21,22は、基端部21a,22aと、基端部21a,22bから互いに離れる方向に帯状に延伸する二つの腕部211a,211b,221a,221bとを含む。アンテナエレメント21の二つの腕部221a,211bの少なくとも一方のインダクタンスが、同じ材質及び略同じ外形の面状導体のインダクタンスに比べて大きい。アンテナエレメント22の二つの腕部221a,221bの少なくとも一方のインダクタンスが、同じ材質及び略同じ外形の面状導体のインダクタンスに比べて大きい。
