Abstract: A coplanar waveguide transmission line and a design method thereof are provided. The coplanar waveguide transmission line includes a first dielectric substrate, a center conductor strip, and two ground conductor strips. The first dielectric substrate has a first surface and a second surface opposite to each other. The center conductor strip and the ground conductor strips are stacked and fixed to the first surface. The center conductor strip includes a first segment and a second segment. A width of the first segment is greater than a width of the second segment, so that the first segment and the second segment form a step structure. A rectangular groove recessed toward the second surface is defined in the first surface, and a part of the center conductor strip is stacked and fixed to a side, distal from the second surface, of the rectangular groove to form a defected ground structure.

Abstract: Aspects of the subject disclosure may include, systems, apparatuses, and methods for determining that a load associated with a transmission medium exceeds a first threshold, wherein the transmission medium guides a first electromagnetic wave that propagates along the transmission medium from a first waveguide device to a second waveguide device without requiring an electrical return path, and based on the determining that the load exceeds the first threshold, enabling an injector to supply power to the transmission medium utilizing a very low frequency (VLF) generator. Other embodiments are disclosed.

Abstract: Apparatuses, methods, and systems for a surface wave based wireless connection to an electronic device are disclosed. One apparatus includes a surface wave guide that supports propagation of electro-magnetic waves over a two-dimensional conductive surface of the surface waveguide, wherein the two-dimensional conductive surface is treated to increase a surface reactance of the two-dimensional conductive surface over a frequency range of the electro-magnetic waves, while maintaining an insertion loss of the surface waveguide below a threshold. A first mode converter operates to couple electro-magnetic waves of a first mode to the two-dimensional conductive surface having a second mode, wherein the electro-magnetic waves of the second mode propagate across the two-dimensional conductive surface of the surface waveguide. At least a portion of the electro-magnetic waves of the two-dimensional conductive surface is coupled to an electronic device through a second mode converter of the electronic device.

Abstract: In accordance with one or more embodiments, a guided wave launcher includes an array of antennas configured to generate near field signals. A controller is configured to: select, in response to a first control signal, at least one of a plurality of guided wave modes; and adjust beam steering parameters of the array of antennas according to the selected one(s) of the plurality of guided wave modes. The near field signals combine to induce a guided electromagnetic wave having the selected one(s) of the plurality of guided wave modes, wherein the first guided electromagnetic wave is guided by the transmission medium and propagates along the transmission medium without requiring an electrical return path.

Abstract: A wave launcher may include a printed circuit board (PCB) that includes a pin that receives a radio frequency (RF) signal. The wave launcher may include a cylinder configured to be electrically coupled to the pin and define an opening. The cylinder may receive the RF signal from the pin, form a transition from coplanar to Goubau line structure with a plate, and generate the surface wave. The wave launcher may include an insulator configured to be physically positioned within the opening and between the cylinder and a power line. The insulator may mechanically isolate the cylinder from the power line and permit the cylinder to launch the surface wave on the power line. The wave launcher may include the plate electrically coupled to a pad and may provide a reference for the pin and the cylinder. The pin and the cylinder may be physically positioned proximate the plate.
