    Abstract: A millimeter waveband filter is provided with a resonator formed by a pair of electric wave half mirrors in a transmission line of a waveguide allowing electromagnetic waves in a predetermined frequency range of a millimeter waveband to propagate in a TE10 mode, and allows frequency components centering on the resonance frequency of the resonator to pass therethrough. A high-pass filter which has a transmission line reduced in size so as to have a cutoff frequency matching an upper limit of a lower rejection band of a filter passband is formed in a transmission line between the end of the waveguide and the electric wave half mirror, thereby increasing the attenuation of the lower rejection band.

    Abstract: An antenna feed with mode suppression includes a transition section, having a window for connecting to an output port of a waveguide and having inner and outer conductors forming a coaxial waveguide that couples energy from the waveguide into a horizontal TE11 mode in the coaxial waveguide. A polarizer section is coupled to the transition section and generates circular polarization from the horizontal mode of the transition section. A radiator section is coupled to the polarizer and provides an output signal for the antenna feed. The transition section includes an electrical short coupling the inner and outer conductors. The electrical short is disposed adjacent to the window of the transition section. A dielectric block is also disposed between the inner and outer conductors and adjacent to the electrical short along the axis of the coaxial waveguide. A surface of the dielectric block is coated with a thin film sheet resistance.

    Abstract: In a gap-mode waveguide embodiment, an interior gap in a tubular waveguide principally condenses a dominant gap mode near the interior gap, and an absorber dissipates electromagnetic energy away from the gap mode. In this manner, the gap mode may dissipate relatively little power in the absorber compared to other modes and propagate with lesser attenuation than all other modes. A gap mode launched into a gap-mode waveguide may provide for low-loss, low-dispersion propagation of signals over a bandwidth including a multimode range of the waveguide. Gap-mode waveguide embodiments of various forms may be used to build guided-wave circuits covering broad bandwidths extending to terahertz frequencies.

    Abstract: A device for absorbing resonances in a large circular cavity such as a microwave rotary joint that utilizes a horizontally positioned resonance absorber positioned in the balun cavity to absorb the resonances or undesired modes. The resonance absorber forms a folded slot with a resistor across its arms to interrupt the circumferential flow of current in the rim of the cavity without affecting the normal desired mode.
