Title
(EN) ANTENNA LAMINATION TECHNIQUE
(FR) UTILISATION DU PROCEDE DE STRATIFICATION POUR FABRIQUER DES ANTENNES
Abstract
(EN)
An antenna system and technique for laminating a dielectric substrate (14) to an antenna housing (12) which prevents separation of the dielectric substrate (14) from the housing (12). This is accomplished by confining an antenna assembly (10) inside a laminating fixture (24). Heat is then applied to the fixture (24). This causes the dielectric substrate (14) to become somewhat plastic and also to expand. This expansion results in great pressure being exerted between the dielectric (14) and the housing (12). When the assembly is allowed to cool, the dielectric (14) adheres to the housing (12). This prevents separation of the housing (12) from the dielectric (14). The result is an antenna assembly (10) which can withstand large temperature extremes without causing an air gap between the dielectric (14) and the housing (12) which would distort the electrical signal transmitted or received by the antenna.

Système d'antenne et procédé permettant de stratifier un substrat diélectrique (14) avec un logement d'antenne (12) pour empêcher que le substrat diélectrique (14) ne se sépare du logement (12). Pour cela, on place l'antenne (10) dans une machine à stratifier (24) que l'on chauffe ensuite. La chaleur provoque une dilatation du substrat diélectrique (14) et le rend quelque peu souple. La dilatation se traduit par une grande pression qui s'exerce entre le diélectrique (14) et le logement (12). Lorsque l'ensemble se refroidit, le diélectrique (14) adhère au logement (12), ce qui empêche le logement (12) de s'en séparer. On obtient ainsi une antenne (10) qui peut résister aux températures les plus extrêmes sans qu'une couche d'air intermédiaire ne se forme entre le diélectrique (14) et le logement (12), ce qui déformerait le signal électrique que transmet ou reçoit l'antenne.
