An arrangement for supplying power to a hollow wave-guide intended for electromagnetic microwaves.

摘要

A hollow waveguide (1) for electromagnetic microwaves supports an adaptation chamber (2) on one side thereof. The chamber includes a frame structure (7) and a cover member (8) and is provided with an adapter line (11). The hollow waveguide is a ridge waveguide having a longitudinally extending ridge (4). The chamber (2) is connected electrically to an outer conductor (18) of a coaxial line (3), through which the arrangement is supplied with power with an electromagnetic microwave (S). One end (12) of the adapter line (11) is connected electrically to the adaptation chamber (2), whereas the other end (16) is connected electrically to a centre conductor (17) of the coaxial line (3). The ridge waveguide (1) is supplied with power from the adaptation chamber (2) through a transverse slot (19) and emits microwaves to the surroundings through longitudinally extending slots (6). The chamber (2) is of simple construction and requires only little space, and can be readily adapted to a desired wavelength of the microwave (S).
