Method and apparatus for coupling an antenna to a device
Paul Shala Henry,Donald J. Barnickel,Farhad Barzegar,Robert Bennett,Irwin Gerszberg,Thomas M. Willis +5 more
TL;DR: In this paper, the authors describe a system that receives, by a feed point of a dielectric antenna, electromagnetic waves from a core coupled to the feed point without an electrical return path, and radiates a wireless signal responsive to the electromagnetic waves being received at the aperture.

Remote distributed antenna system
Farhad Barzegar,Donald J. Barnickel,George Blandino,Irwin Gerszberg,Paul Shala Henry,Thomas M. Willis +5 more
TL;DR: In this article, a distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas.
Patent
Method and apparatus for sensing a condition in a transmission medium of electromagnetic waves
TL;DR: In this article, the authors describe a device that facilitates transmitting electromagnetic waves along a surface of a wire that facilitates delivery of electric energy to devices, and sensing a condition that is adverse to the electromagnetic waves propagating along the surface of the wire.

Method and apparatus that provides fault tolerance in a communication network
Paul Shala Henry,Robert Bennett,Irwin Gerszberg,Farhad Barzegar,Donald J. Barnickel,Thomas M. Willis +5 more
TL;DR: In this article, a system for detecting a fault in a first wire of a power grid that affects a transmission or reception of electromagnetic waves that transport data and that propagate along a surface of the first wire is described.

Guided-wave transmission device with non-fundamental mode propagation and methods for use therewith
Paul Shala Henry,Robert Bennett,Irwin Gerszberg,Farhad Barzegar,Donald J. Barnickel,Thomas M. Willis +5 more
TL;DR: In this article, a coupler couples the first electromagnetic wave to a single wire transmission medium having an outer surface, to forming a second electromagnetic wave that is guided to propagate along the outer surface of the single-wire transmission medium via at least one guided wave mode that includes an asymmetric or non-fundamental mode having a lower cutoff frequency.

Cancellation system for frequency reuse in microwave communications
TL;DR: In this paper, a spatial demultiplexing technique was proposed to cancel co-channel interference and transmitter leakage in microwave communications systems, and substantial improvements in frequency reuse were achieved by canceling cochannel interference.
