Title (EN) METHOD AND SMALL-SIZE ANTENNA WITH INCREASED EFFECTIVE HEIGHT
(FR) PROCEDE POUR AUGMENTER LA HAUTEUR EFFECTIVE D'UN ENSEMBLE ANTENNE COMPACT, PROCEDE ASSURANT L'EFFET DIRECTIONNEL DE L'ENSEMBLE ANTENNE COMPACT ET ENSEMBLES ANTENNES COMPACTS DE MISE EN OEUVRE DE CES PROCEDES
Abstract: front page image
(EN)The invention relates to radio technology and can be used for developing compact antenna assemblies for various uses. Said invention makes it possible to considerably increase the effective height of the antenna and to develop a directional aerial assembly having the dimensions which are less than quarter of wave length and oriented in the propagation direction of radiated and absorbed waves. The inventive compact antenna assembly comprises an oscillatory circuit consisting of a reactive component (8) and an inductance coil. Said reactive component (8) is embodied in the form of a condenser provided with a pair of metallic plates (11). A space between the plates is filled with a material (9) containing particles (10) of conducting material separated by a dielectric filling material. The distance between the plates (11) is chosen such that it is less than $g(l)/4, where $g(l) is a wave length of actuating signals The conducting material is selected with respect to a formula ($g(v)$g(r)?2¿$g(e)$g(m)/x¿o?)* 10?-11¿$m(G)1, (1/$g(r)$g(v))10?10¿>>$g(e), where $g(v) is the actuating signal frequency, $g(r) is the electrical resistivety of conducting material (Ohm*m), $g(e),$g(m) are respectively the relative electrical and magnetic conductivity of the medium, x¿o? is a minimal dimension of the cross section of a particle of conducting material and oriented perpendicularly to the actuating electric-field vector.
(FR)Cette invention concerne un dispositif radio et peut être utilisée dans la mise au point d'ensembles antennes compacts prévus pour diverses applications. Cette invention permet d'augmenter considérablement la hauteur effective d'une antenne et de mettre au point l'antenne directionnelle dont les dimensions, selon l'axe de propagation des ondes rayonnées et absorbées, sont inférieures au quart d'onde. L'ensemble antenne compact de cette invention comprend un circuit oscillant constitué d'un composant réactif (8) et d'une bobine d'induction. Le composant réactif (8) se présente sous forme d'un condensateur à deux plaques métalliques (11) prenant en sandwich un matériau (9) contenant des particules (10) d'une substance conductrice, séparées par une charge diélectrique. La distance entre les plaques (11) est inférieure à $g(l)/4, $g(l) étant la longueur d'onde des signaux actifs. La substance conductrice est telle que ($g(v)$g(r)?2¿$g(e)$g(m)/x0) * 10?-11¿ $m(G) 1, pour (1/$g(r)$g(v))10?10¿ >>$g(e), $g(v) étant la fréquence du signal actif, $g(r) la résistance électrique spécifique de la substance conductrice (Ohm.m), $g(e), $g(m) représentant respectivement la conductivité électrique relative et la conductivité magnétique du milieu, x¿0? la dimension minimale en coupe d'une particule de substance conductrice, perpendiculairement au vecteur du champ électrique de mis en oeuvre.
