Various embodiments provide for waveguide assemblies which may be utilized in wireless communication systems. Various embodiments may allow for waveguide assemblies to be assembled using tools and methodologies that are simpler than the conventional alternatives. Some embodiments provide for a waveguide assembly that comprises a straight tubular portion configured to be shortened, using simple techniques and tools, in order to fit into a waveguide assembly. For instance, for some embodiments, the waveguide assembly may be configured such that the straight portion can be shortened, at a cross section of the portion, using a basic cutting tool, such a hacksaw. In some embodiments, the straight portion may be further configured such that regardless of whether the straight tubular portion is shortened, the waveguide assembly remains capable of coupling to flanges, which facilitate coupling the straight tubular portion to connectable assemblies, such as other waveguide assemblies, radio equipment, or antennas.

Gap-Mode Waveguide

Номер: US20120243823A1
Автор: Kirk S. Giboney
Принадлежит: Individual

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.

The second waveguide is provided with a second recessed part which has an opening with a same shape as the second opening and has a bottom part formed in a second direction as seen from the opening. The first/second waveguides are united in a manner such that, positions of the bottom parts of the first/second recessed parts are different from each other in a direction differing from the first/second directions, and the first/second recessed parts connect with each other at the respective bottom parts.

A connection structure of a waveguide includes a rod-like dielectric, and an outer conductor. A three-dimensional component includes a connection surface, an insertion hole, and a corner which forms an opening edge of the insertion hole over an entire circumference on the connection surface, the connection surface at least partially including a conductive region to which a connection enlarged portion of the outer conductor is connected, the insertion hole having conductivity over an entire circumference of an inner surface, the corner having conductivity and being conducted with the inner surface of the insertion hole. In a state where the waveguide and the three-dimensional component are connected with each other, the connection enlarged portion is electrically conducted with the inner surface of the insertion hole through electrical connection with the connection surface and the corner, and smooth connection is made at the corner.
