Systems and methods of waveguide assembly

Номер: US20120086527A1

Автор: Edwin NEALIS, Jayesh Nath

Принадлежит: Aviat US Inc

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.

Planar circuit to waveguide transition

Автор: Akimichi Hirota, Takeshi Yuasa, Tetsu Owada, Tetsuya Oba

Openings are formed by removing part of a ground conductor, and a differential signal line including signal line conductors is configured with some of the openings. In addition, a metal block is mounted thereon to cover the opening to thus configure a waveguide using the metal block and ground conductor as wall surfaces. A planar circuit to waveguide transition according to the above can achieve traveling wave conversions from a waveguide mode to a slot mode, and from the slot mode to a differential mode without utilizing resonance, which makes it possible to align a dominant direction of an electric field by the three ones; thus, a wider bandwidth can be expected. Thus, the wider bandwidth can be achieved with a simple layer structure.
