    • A microwave applicator device for continuous heat treatment of elongate products comprises an applicator housing that defines a generally rectangular waveguide cavity and at least one excitation system for exciting the cavity with microwaves propagating in TE.sub.01 transverse electric mode, the system including at least one microwave generator associated with a feed waveguide connected to the cavity via a window formed through a wall of the cavity. The front and rear walls of the feed waveguide are respectively connected to the front and rear edges of the window, and the feed waveguide is associated with a guide flap extending in the cavity in the vicinity of the rear edge of the window, and with a guide member provided substantially facing the window. The front and rear walls of the feed waveguide include respective front and rear connection portions situated in the connection zone for connection with the window, and each being curved forwards substantially in the form of an arc of a circle, the guide flap is situated substantially in line with the rear connection portion, and the excitation system includes means for adjusting wave coupling.
