Abstract
An apparatus for the propagation of microwaves, particularly ultrahigh frequency waves. A substrate has formed therein a cavity open on one of the sides of the substrate. A membrane is deposited on the substrate above the cavity. At least one transmission line is located on the membrane which is able to propagate an ultrahigh frequency wave. An integrated circuit for rigidifying the membrane is fixed to the transmission line or to the membrane on the side where the line is located.
