Abstract
A high frequency electrical signal control device comprises a transmitter for generating a high frequency electrical signal, a receiver, a transmission line for propagating the electrical signal, and a structure for radiating the electrical signal propagated through the transmission line to the space or receiving a signal from the space. The degree of coupling of the electrical signal between the space and the transmission line provided by the structure can be variably controlled.

25. An electromagnetic wave control device, comprising a substrate provided thereon with:
-
a transmitter for outputting an electromagnetic wave having a frequency ranging from 30 GHz to 30 THz; a transmission line for propagating the electromagnetic wave output from the transmitter; a receiver for receiving through the transmission line an electromagnetic wave with a frequency in the above range; and an antenna for radiating the electromagnetic wave output from the transmitter and propagated through the transmission line to an outer space or receiving an electromagnetic wave with a frequency in the above range from the outer space and inputting it into the receiver through the transmission line, wherein the device has a switch for selecting either one of a first state where the electromagnetic wave output from the transmitter is directly input into the receiver through the transmission line without being radiated to the outer space, and a second state where the electromagnetic wave output from the transmitter to the transmission line is radiated to the outer space through the antenna or an electromagnetic wave with a frequency in the above range is received by the antenna and input into the receiver through the transmission line. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
