Abstract: An apparatus includes a measurement structure for performing measurements of an RF device. The measurement structure includes an aperture in a conductive surface of the RF device and a conductive projecting region projecting into the aperture from a conductive perimeter of the aperture and electrically connected to that conductive perimeter. The aperture has a similar width in all dimensions. A combined shape of the aperture and the conductive projecting region does not possess even rotational symmetry about a point where a signal conductor will be placed on the conductive projecting region in order to conduct RF energy between the measurement structure and an external measurement instrument for performing the measurements. The measurement structure may be used for performing measurements of a multimode resonator, the measurements comprising one or more of resonant frequencies and quality factors of resonant modes of the resonator.

Abstract: A first dielectric resonator component is joined to a second dielectric resonator component by bonding a first face of the first dielectric resonator component to a second face of the second dielectric resonator component. The first face has a first coupling aperture formed by removing a portion of a coating of first conductive material from the first dielectric resonator component, and the second face has a second coupling aperture formed by removing a portion of a coating of second conductive material from the second dielectric resonator component. The first coupling aperture and said second coupling aperture are aligned with one another when said first face is bonded to the second face. The first dielectric resonator component, which is slab-shaped, and the second dielectric resonator component, which is generally cubed-shaped, form a linear stack having two end faces and four side faces. A first hole is provided at a point along a center line of a side face of the first dielectric resonator component in the direction of orientation of the linear stack, and a second hole is provided substantially in the center of a side face of the second dielectric resonator component to tune a resonant frequency of the pair of joined dielectric resonator components.

Abstract: A filter comprises a dielectric resonator element and a cylindrical waveguide cavity having a corrugated tube structure that surrounds the dielectric resonator element such that an outer encircling wall surface of the dielectric resonator element is in contact with an inner sidewall of the corrugated tube structure. The corrugated tube structure includes one or more spaced-apart corrugations configured to provide a spring-like action to controllably expand and contract the corrugated tube structure so that the dielectric resonator element can be controllably inserted and clamped within the cylindrical waveguide cavity. The geometry of the spaced-apart corrugations can be selected to define a rotationally asymmetric corrugated tube structure configured to split a plurality of fundamental modes of electromagnetic waves within the filter.

Abstract: An apparatus includes a filtenna. The filtenna includes a block having a waveguide formed therein, and having first and second ends, wherein the first end is closed and the second end radiates to free space. The filtenna also includes multiple patch elements suspended within the waveguide, ordered from a first patch element at the first end of the waveguide to a final patch element at the second end of the waveguide. The filtenna further includes one or more ports at the first end of the waveguide. Each of the one or more ports is electrically coupled to the first patch element, and is for coupling to a corresponding antenna polarization. A dual-polarized filtenna is possible, as are transmitters, receivers, base stations, and the like. An array of filtennas may be created and used, and the filtenna(s) may be used for transmission, reception, or both.
