Abstract: A dielectrically loaded rectangular waveguide to air-filled rectangular waveguide adapter and right-angle waveguide probe antenna with a bandwidth greater than 15% of the center frequency of the operating band, as defined by a return loss over the frequency range better than or equal to −20 dBV. This invention is most relevant to a right-angle coaxial to a dielectrically loaded rectangular waveguide, followed by an air-filled rectangular waveguide transition. The dielectrically loaded rectangular waveguide to air-filled rectangular waveguide adapter is comprised of a relatively narrow dielectrically loaded rectangular waveguide section, a relatively wide air-filled rectangular waveguide section following the dielectrically loaded rectangular waveguide section of equal height, and a right-angle waveguide probe antenna. The probe antenna is comprised of a tapered cylinder that results in an inverted conical shape resembling a V-frame. The resultant “V-frame probe” is connected to a coaxial feed cable and extends into the dielectrically loaded waveguide section through an aperture. The dielectrically loaded waveguide transitions into an air-filled rectangular waveguide and is sized such that it the impedance of the dominant TE mode of frequencies supported by the waveguide is preserved without causing unintended mode conversion. The V-frame probe operates as a TE10 mode waveguide radiator, and is sized and positioned such that the impedance of the probe antenna is closely matched to the impedance of the waveguide across a wider frequency band.

Abstract: Aspects of the subject disclosure may include, for example, a coupling device including a receiving portion that receives a radio frequency signal conveying data from a transmitting device. A magnetic coupler magnetically couples the radio frequency signal to a transmission medium as a guided electromagnetic wave that is bound by an outer surface of the transmission medium. A cap includes a dielectric portion that secures the transmission medium adjacent to the magnetic coupler and a reflective plate that reduces electromagnetic emissions from the magnetic coupler. Other embodiments are disclosed.

Abstract: Embodiments herein describe a high-speed communication channel in a PCB that includes a dielectric waveguide coupled at respective ends to coaxial vias. The dielectric waveguide includes a core and a cladding where the material of the core has a higher dielectric constant than the material of the cladding. Thus, electromagnetic signals propagating in the core are internally reflected at the interface between the core and cladding such that the electromagnetic signals are primary contained in the core. The coaxial vias include a center conductor and an outer conductor (or shield) which extend through one or more layers of the PCB. One of the coaxial vias radiates electromagnetic signals into the dielectric waveguide at a first end of the core while the other coaxial via receives the radiated signals at a second end of the core.
