(EN) PARTIALLY SHORTED DOUBLE RING MICROSTRIP ANTENNA HAVING A MICROSTRIP FEED
(FR) ANTENNE MICRORUBAN A DOUBLE BAGUE PARTIELLEMENT COURT-CIRCUITEE COMPORTANT UNE LIGNE MICRORUBAN
Abstract
(EN)
An antenna for a convenient and economical installation in a small volume within a computer or other electronic equipment. The microstrip antenna includes a ground plane, a radiating patch, and a dielectric layer separating them. A partially short-circuited edge has a plurality of short-circuited sections formed thereon. A microstrip feed line is formed on the partially short-circuited edge, positioned between a first short-circuited section and a second short-circuited section. Preferably, a rectangular ring is formed in the radiating patch, offset so that it is closer to the partially short-circuited edge than to the radiating edge opposite thereto. The microstrip feed line provides an economical connection to a circuit board, and allows positioning the antenna so that the ground plane faces adjacent metal surfaces or circuits.

L'invention concerne une antenne permettant de réaliser une installation pratique et économique dans un petit volume dans un ordinateur ou tout autre matériel électronique. L'antenne microruban comprend un tapis de sol et une plaque rayonnante séparés par une couche diélectrique . Un bord partiellement court-circuité comprend une pluralité de sections court-circuitées . Une ligne microruban est formée sur le bord partiellement court-circuité, positionné entre une première section court-circuitée et une deuxième section court-circuitée. De préférence, une bague rectangulaire est formée dans la plaque rayonnante, décalée de manière à être plus proche du bord partiellement court-circuité que du bord rayonnant opposé à ce dernier. La ligne microruban assure une connexion économique à une plaquette de circuits, et permet de positionner l'antenne de manière à ce que le tapis de sol soit adjacent aux surfaces métalliques ou aux circuits.
