LINEARLY EXTENDED DEVICE FOR LARGE-SURFACE MICROWAVE TREATMENT AND FOR LARGE SURFACE PLASMA PRODUCTION

摘要

The aim of the invention is to provide an alternative to the intensive treatment of a product to be treated, especially plasma treatment, in specif ic areas only. To this end, the invention provides a device for producing microwaves for treating workpieces, comprising at least one microwave antenn a with a extended conductor for producing electromagnetic alternating fields, a housing that essentially extends over the length of the conductor, and a extended microwave decoupling area which follows the conductor and which is located in the housing. The housing is formed by at least one resonant cavit y, which has a long shape and follows the course of the microwave antenna. The resonant cavity has at least one tapering, closed, first crown area and the decoupling area essentially extends in the focussing area of the resonant cavity. An at least non-divergent housing area adjoins the resonant cavity.< /SDOAB>
