摘要： It is provided a waveguide E-plane band-pass filter comprising a tubular, electrically conductive waveguide body. An electrically conductive foil is arranged in the waveguide body and extending along a longitudinal direction of the waveguide body, the foil comprising a plurality of resonator openings. Furthermore, the waveguide body comprises at least one ridge protruding from an inner wall of the waveguide body and extending longitudinally along the longitudinal direction of the waveguide body. The foil is in mechanical contact with said at least one ridge and arranged to divide an inner volume of the waveguide body into two portions. It is also provided a diplexer, a radio transceiver, and a method for filtering a signal using such a filter.

摘要： A polarisation-preserving filter for a dual-polarised waveguide with a basic body that is circular in cross section. Arranged in the interior of the basic body is a plurality of nubs, wherein the nubs are grouped in several rings, due to which a first, predetermined frequency band can be transmitted unobstructed and the transmission of a second, predetermined frequency band can be blocked.

摘要： A ridge waveguide filter which is formed of metallized blind vias in a plurality of contiguous layers of a dielectric medium including low temperature cofired ceramic (LTCC), high temperature cofired ceramic (HTCC) or organic printed wiring boards (PWB) in the fabrication of the waveguide sidewalls and solid ground planes to provide top and bottom walls as well as in the formation of a plurality of ridge waveguide sections in an embedded ridge waveguide structure. Patterns of conductive metal are selectively printed on the outer surface of certain dielectric layers to electrically short all the vias in the ridge waveguide sections and the adjacent wall vias so that the elements behave as though they comprise a solid metal structure.

摘要： A high-frequency communication apparatus has a case containing a transmitter-receiver including circuit elements. A functional structure capable of confining radiation energy radiated by unnecessary radio wave source to prevent the radiation energy from interfering with the operations of the transmitter-receiver is formed on at least one of the walls of the case by forming a plurality of projections in regular arrangement by press working. The circuit elements of the transmitter-receiver are packed in the case to suppress the undesired electromagnetic coupling of internal and external electromagnetic waves with the circuit elements of the transmitter-receiver.

摘要： A waveguide filter for use in a microwave oven having a plurality of metallic plates disposed in a waveguide in substantially parallel to side walls of the waveguide. The metallic plates are provided in the upper and lower edges thereof with a series of openings at a constant interval so as to provide a corrugated configuration. First members are disposed for providing a certain spacing between adjacent ones of the metallic plates and holding the metallic plates substantially in parallel to one another; and second members including metal members are disposed between the side walls of said waveguide and the ones of the metallic plates adjacent the waveguide side walls for creating a substantially uniform clearance between the upper and lower edges of the metallic plates and the upper and lower walls of the waveguide and for holding the metallic plates substantially in parallel to the waveguide side walls.
