Title (EN) ANTENNA DEVICE
(FR) DISPOSITIF D'ANTENNE
(JA) アンテナ装置
Abstract:
(EN) Provided is an antenna device whereby both directivity control and miniaturization can be achieved. A power feed element 10 and a parasitic element 20 face each other at a predetermined interval. A control circuit 30 changes the electrical length of the parasitic element 20, while maintaining the position and the physical length of the parasitic element 20. For instance, the parasitic element 20 is operated as a waveguide for the power feed element 10 by connecting the parasitic element 20 and a capacitor 22 to each other. Furthermore, the parasitic element 20 is operated as a reflector for the power feed element 10 by connecting the parasitic element 20 and a coil 23 to each other.
(FR) L'invention concerne un dispositif d'antenne permettant d'obtenir à la fois une commande de directivité et une miniaturisation. Un élément d'alimentation électrique (10) et un élément parasite (20) se font face à un intervalle prédéterminé. Un circuit de commande (30) fait varier la longueur électrique de l'élément parasite (20), tout en maintenant la position et la longueur physique de ce dernier. À titre d'exemple, l'élément parasite (20) sert de guide d'onde à l'élément d'alimentation électrique (10) en connectant l'élément parasite (20) à un condensateur (22). En outre, l'élément parasite (20) sert de réflecteur à l'élément d'alimentation électrique (10) en connectant l'élément parasite (20) à une bobine (23).
(JA) 指向性の制御と小型化とを両立させることができるアンテナ装置を提供する。 給電素子10と無給電素子20とを所定間隔で対向させる。制御回路30は、無給電素子20の位置及び物理長を維持しつつ当該無給電素子20の電気長を変化させる。例えば、無給電素子20とコンデンサ22とを接続することにより、無給電素子20を給電素子10の導波器として動作させる。また、無給電素子20とコイル23とを接続することにより、無給電素子20を給電素子10の反射器として動作させる。
