Electromagnetic wave propagation apparatus and electromagnetic wave interface

摘要

An electromagnetic wave propagation apparatus has a planar propagation medium including a planar conductor, a first planar dielectric, a planar mesh conductor, and a second planar dielectric being overlaid on each other in order; at least one electromagnetic wave input port for the planar propagation; a power supply station that supplies the planar propagation medium with an electromagnetic wave via at least one electromagnetic wave input port; and at least one power receiving apparatus for a second planar dielectric of the planar propagation medium that includes an electromagnetic wave interface and a power receiving circuit. A dielectric board has multiple conductor patterns as the electromagnetic wave interface. At least one connection means is between the conductor pattern and the power receiving circuit. At least one short-circuit means between the conductor patterns is at an end of the conductor pattern.

1. An electromagnetic wave propagation apparatus that propagates an electromagnetic wave as one of electric power and information between a base station and a terminal, the electromagnetic wave propagation apparatus comprising:
a planar propagation medium including a planar conductor, a first planar dielectric, a planar mesh conductor, and a second planar dielectric that are stacked on each other in order; at least one electromagnetic wave input port that functions as a first interface to connect the base station with the planar propagation medium; and an electromagnetic wave interface that is provided on the second planar dielectric and functions as a second interface to connect the terminal with the planar propagation medium, wherein the electromagnetic wave interface includes a planar dielectric board and a plurality of planar conductor patterns disposed in parallel so as to sandwich portions of the dielectric board between adjacent ones of the conductor patterns; wherein the conductor patterns include a first conductor pattern that is disposed closer to the planar propagation medium than the other conductor patterns; wherein the first conductor pattern has a polygonal shape with at least a first corner and a second corner; wherein a first through via is provided between the first conductor pattern and the terminal in a region proximal to the first corner of the first conductor pattern; wherein a first short via is provided to electrically short-circuit the conductor patterns in the region proximal to the first corner of the first conductor pattern; wherein a second through via is provided between the first conductor pattern and the terminal in a region proximal to the second corner of the first conductor pattern; wherein the terminal includes a power receiving circuit connected to the electromagnetic wave interface; and wherein each of the first and second through vias produce reception power and the terminal is configured to synthesize the reception powers supplied with a given phase difference.
