A package for embedding one or more electronic components comprises a carrier structure a silicon-based carrier layer, one or more electronic components embedded in one or more cavities formed in the carrier layer, and a cover structure arranged on top of the carrier structure. The cover structure comprises a cover layer and one or more cavities formed in the cover layer. An antenna element and/or a waveguide for connection to an antenna element is formed in and/or on top of the cover layer and coupled to the one or more cavities.

A waveguide includes: a dielectric including two surfaces, an electric field intersecting with the two surfaces; metal-plating layers coating the two surfaces of the dielectric, the electric field intersecting with the two surfaces; and a protective layer coating a periphery of the dielectric including the two surfaces coated with the metal-plating layers. A wireless transmission system includes: a sender configured to send a high-frequency signal; and a receiver configured to receive the high-frequency signal. The waveguide is used as a waveguide configured to transmit the high-frequency signal between the sender and the receiver in the wireless transmission system.

A waveguide is provided that includes an elongate dielectric inner region, and an electrically conducting outer region spaced apart from the dielectric inner region. The dielectric inner region may be arranged to be flexible, and in some examples may be formed from powdered dielectric contained in a polymer tube or matrix, or in other examples may be formed from a plurality of segments. In some examples of the waveguide, each segment may be formed to have lenticular end faces, and may be formed from sintered BaTi4O9.

According to some embodiments, a waveguide cable includes a dielectric core and a conducting layer surrounding the dielectric core. A first antenna may be provided at a first end of the waveguide cable to receive a digital signal and to propagate an electromagnetic wave through the dielectric core. A second antenna may be provided at a second end of the waveguide cable, opposite the first end, to receive the electromagnetic wave from the dielectric core and to provide the digital signal.

An interconnection system for effecting the rapid connection and disconnection of facing components comprises male and female connectors. A first end of the male connector is generally rectangular. The second end has a cylindrical portion extending inwardly, an inner face, and radially extending flanges. Recesses are formed between the flanges and the first end. The female connector is configured to mate with the male. When in the locked state the flanges of the male connector form a coplanar coupling with receivers of the female connector.

A bending mechanism for flexible waveguide uses a combination of an elongate arm (1), two short bracket arms (3 & 7) and a gear train (5, 11, 13 & 9) linking the bracket arms to bend a flexible waveguide (24) over a range of positions. The bend is formed to the shape of a circular arc the radius of which varies with the position. Each short bracket arm is pivotally connected (15 & 17) to a respective end of the elongate arm and to a respective one of the waveguide's two end flanges (23 & 25). Each bracket arm contains a gear that rotates with the respective bracket arm about the bracket arm's pivot; and an even number of gears interlinks those gears whereby pivotal movement of one of the flanges in a clockwise direction produces an effective relative pivotal movement of the other flange. The bending mechanism allows for as much as 180 degrees of repetitive reciprocal rotation of one flange relative to the other without imposing significant stress on the flexible waveguide, providing an ideal long lasting interface between a mechanically scanning microwave antenna and a microwave transmitter/receiver.

An unsymmetrically corrugated TE.sub.01 mode circular waveguide bend. Unsetrical corrugations approximately one-quarter wavelength deep are utilized to suppress energy transfer to other modes inherent in smooth wall circular guide bends. The corrugations are comprised of a plurality of adjacent internal ridges and valleys having substantially parallel walls such that the distance between the parallel walls of the internal ridges are at least twice the distance between the parallel walls of the internal valleys.
摘要:
Method and apparatus for manufacturing long lengths of flexible waveguides which have an inner wall of a helically wound insulated conductor covered by insulating or metal tape over which a thermoplastic sheath is extruded, in which the insulated conductor is wound in a helix and advanced successively through tape winding and sheath extruding machines at a rate which permits each operation to be continuous. Subsequent to the extrusion of the sheath it is cooled and the waveguide is wound on a bobbin. Armoring and protective layers may be added to the waveguide prior to or subsequent to winding of the waveguide on the bobbin.
摘要:
A waveguide having an internal wall formed by a plurality of insulated straps of conductive material wound on edge in a helix so that the major surfaces thereof face each other, each strap being of a different cross-section or being differently disposed so as to leave a space between adjacent major surfaces. The helix is covered by a sheath of flexible insulating material which may be covered by an armor which, in turn, may be covered by a protective layer of flexible insulating material.
