Title: Diversity antenna for unii access point
Inventor: FRANK TIMOTHY
IPC: H01Q25/00
Filed: 2003-03-04
Granted: 2009-09-01
Abstract: A combination of near omni-directional antennas and internal patch antennas, all built into an access point in accordance with FCC requirements. Typically a printed antenna array is used for the near omni-directional antenna, and the internal patch antenna is a TM10 mode stacked patch antenna. A mechanical detect switch changes antenna types automatically, depending on the rotation state of the antenna system. Alternately, a configuration utility enables a user to select the antenna type for the access point when it is installed in the field. This arrangement gives the UNII access point flexibility to be mounted in various orientations and match the characteristics of the antenna to the installation requirements.

Abstract: L'invention concerne un varactor ferroélectrique permettant de commuter une capacité en parallèle. On utilise comme substrat du silicium à résistivité élevée sur lequel sont déposées une couche SiO¿2? et une couche métallique comportant des motifs. Une couche de film mince ferroélectrique déposée sur le substrat sert à implanter le varactor. Une électrode métallique supérieure déposée sur la couche de film mince ferroélectrique forme une ligne de transmission de guide d'ondes coplanaire. On utilise la capacité formée par les conducteurs de terre à grande surface de l'électrode métallique supérieure et de la couche métallique inférieure pour monter en série le varactor ferroélectrique et le grand condensateur défini par les conducteurs de terre. Le grand condensateur sert de court-circuit à la masse, ce qui rend superflus les trous d'interconnexion. Le concept de commutation des états de marche et d'arrêt repose sur l'accordabilité diélectrique des films minces ferroélectriques. A 0 V, le varactor présente la capacité maximum, qui entraîne la mise à la terre du signal et isole ainsi la sortie de l'entrée ; dans ce cas, le commutateur est à l'état d'arrêt. L'application d'une faible tension au conducteur central du guide d'ondes coplanaire réduit la capacité du varactor, ce qui permet la transmission du signal et entraîne la mise en marche du dispositif. Une telle dérivation varactor permet de résoudre la plupart des problèmes que posent les commutateurs en parallèle RF MEMS.
