Claim Text:
1. A dielectric waveguide filter for a transmission of an RF signal comprising: a first solid and separate block of dielectric material defining a first longitudinal axis and including a plurality of exterior surfaces covered with a layer of conductive material; one or more first open slots extending into one or more of the plurality of exterior surfaces and the dielectric material and separating the first solid and separate block of the dielectric material into a plurality of first resonators; one or more first RF signal transmission bridges of the dielectric material on the first solid and separate block of dielectric material being co-linear with the one or more first open slots respectively and defining a first path for the transmission of the RF signal between each of the plurality of first resonators in a direction along the first longitudinal axis; a first RF signal transmission window defined in the layer of conductive material in a region of one of the plurality of first resonators; a second solid and separate block of dielectric material defining a second longitudinal axis and including a plurality of exterior surfaces covered with a layer of conductive material; one or more second open slots extending into one or more of the plurality of exterior surfaces and the dielectric material of the second solid and separate block and separating the second solid and separate block of dielectric material into a plurality of second resonators; one or more second RF signal transmission bridges of the dielectric material on the second solid and separate block of dielectric material co-linear with the one or more second open slots and defining a second path for the transmission of the RF signal between each of the plurality of second resonators in a direction along the second longitudinal axis; a second RF signal transmission window defined in the layer of conductive material of the second solid and separate block in a region of one of the plurality of second resonators; and the first and second solid and separate blocks of dielectric material being coupled to each other in a relationship wherein one of the plurality of exterior surfaces of the second solid and separate block of dielectric material is abutted against one of the plurality of exterior surfaces of the first block of dielectric material and the first and second RF signal transmission windows are aligned with each other and define a third path for the transmission of the RF signal between the first and second solid and separate blocks of dielectric material in a direction normal to the first and second longitudinal axis.
