In a method of fabricating a tuning door for resonant cavity, firstly contact fingers are formed around the edge of a conductive plate and the plate is then fixed to a support by, for example, double sided adhesive tape. The conductive plate is part of the interior surface of the resonant cavity. The fingers may be formed in one operation, for example, by photo etching and are fully integral with the active surface to give optimum electrical conduction between them. Other types of high frequency apparatus where contact fingers are used to provide electrical conduction between a moveable wall and an adjacent conductive surface may also make use of the invention.

Procédé servant à fabriquer un volet d'accord pour une cavité résonante et consistant d'abord à créer des doigts de contact (10) autour du bord d'une plaque conductrice (9) et à fixer ensuite cette plaque (9) sur un support (12) au moyen, par exemple, de bandes adhésives double face (11). Cette plaque conductrice (9) fait partie de la surface intérieure de la cavité résonante. On peut créer ces doigts en une opération, par exemple, par photogravure et ils sont totalement solidaires de la surface active, de manière à produire une conduction électrique optimum entre eux. L'invention peut également concerner d'autres types de dispositif haute fréquence dans lesquels on utilise des doigts de contact afin d'obtenir une conduction électrique entre une paroi mobile et une surface conductrice contiguë.
