Title (EN) LOW PROFILE HELICAL PLANAR RADIO ANTENNA WITH PLURAL CONDUCTORS
(FR) ANTENNE RADIO PLAN HELICOIDALE A PROFIL BAS COMPRENANT UNE PLURALITE DE CONDUCTEURS
Abstract:
(EN) A low profile, compact planar antenna having an approximately flat, dual helical or helix shape is affixed to a supporting substrate. The resonant frequency of the device is determined by parameters including and not limited to length, width, and pitch angle of the helix. An additional helical element is added to induce a second resonant frequency and increase bandwidth. The antenna has an omni-directional radiation pattern, is highly efficient, and is provided in a compact profile suitable for use in a small battery operated device, such as water, gas or electricity meters as well as industrial sensors and security devices.
(FR) L'invention concerne une antenne plan compacte à profil bas présentant une forme hélicoïdale ou à double hélice sensiblement plate fixée à un substrat de support. La fréquence résonante du dispositif est déterminée au moyen de paramètres, notamment la longueur, la largeur et l'angle de pas de l'hélice. Un élément hélicoïdal supplémentaire est ajouté afin d'induire une seconde fréquence résonante et d'augmenter la largeur de bande. L'antenne présente un diagramme de rayonnement omnidirectionnel, est très efficace et est dotée d'un profil compact approprié pour être utilisé dans un dispositif fonctionnant avec une petite batterie, tel que des compteurs d'eau, de gaz ou d'électricité ainsi que des capteurs industriels et des dispositifs de sécurité.
