Abstract
Official abstract text for this publication.
In an end surface 32 b of the second transmission line forming body 32 forming a second waveguide 30 , the height of a central region 33 which includes an opening of the second transmission line 30 b is a reference plane. A depressed portion 32 e that is depressed to a depth greater than the length of a thread portion of a screw 205 from the reference plane is provided in a region outside the central region 33 and includes a screw hole forming position. A screw hole 32 d for fixing an external circuit 200 to be connected is provided at the screw hole forming position in the depressed portion 32 e . The height of a region, which is excluding the depressed portion 32 e and is further away from the central region 33 than the screw hole forming position, is equal to the reference plane.
First claim
Opening claim text (preview).
What is claimed is: 1. A millimeter waveband filter comprising: a first waveguide including a transmission line with a size that is capable of transmitting electromagnetic waves in a predetermined frequency range of a millimeter-wave band in a TE10 mode; a second waveguide that includes a first transmission line which has a size that is greater than an outside size of the first waveguide and is capable of transmitting the electromagnetic waves in the predetermined frequency rang…
