ELECTROMAGNETIC WAVE TRANSMISSION SHEET AND ELECTROMAGNETIC WAVE TRANSMISSION DEVICE
First Claim
1. An electromagnetic wave transmission sheet which is connected to an AC power source and transmits an electromagnetic wave,wherein an edge portion which defines a planar shape has two long end sides which have parallel portions extending in parallel to each other, and two short end sides which have parallel portions extending in parallel to each other and are shorter than the long end sides,the two long end sides and the two short end sides are reflection terminals,the parallel portion of at least the first short end side out of the two short end sides includes a first portion and a second portion,an electromagnetic wave which propagates in a direction substantially parallel to the parallel portion of the long end sides includes:
- a first standing wave formed by a traveling wave directed toward the first portion of the first short end side and a reflected wave reflected by the first portion and directed toward the second short end side; and
a second standing wave formed by a traveling wave directed toward the second portion of the first short end side and a reflected wave reflected by the second portion and directed toward the second short end side, andthe positions of the antinodes of the first standing wave and the second standing wave in a direction substantially parallel to the parallel portions of the long end sides are deviated from each other by 1/4 of the wavelength of an electromagnetic wave propagating through the electromagnetic wave transmission sheet.

Abstract
An edge portion which defines a planar shape has two long end sides (108a, 108b) which extend in parallel to each other, and two short end sides (107, 109) which have parallel portions extending in parallel to each other. The two long end sides and the two short end sides are reflection terminals. The parallel portion of the first short end side (107) includes a first portion (107a) and a second portion (107b). The positions of the antinodes of a first standing wave formed by a traveling wave directed toward the first portion (107a) and a reflected wave of the traveling wave and a second standing wave formed by a traveling wave directed toward the second portion (107b) and a reflected wave of the traveling wave in a direction substantially parallel to the long end sides (108a, 108b) are deviated by 1/4 of the wavelength of an electromagnetic wave propagating through an electromagnetic wave transmission sheet.
