実時間送受信装置
Document Type and Number:
Japanese Patent JP7308312
Kind Code:
B2
Abstract:
To provide a real time transmitting/receiving device that can transmit and receive electromagnetic waves with high accuracy by suppressing the generation of noise caused by directly receiving electromagnetic waves transmitted by a transmitting antenna, in real time transmitting/receiving devices that transmit and receive electromagnetic waves with high frequencies equal to or more than a millimeter wave band.SOLUTION: A real time transmitting/receiving device 100 includes a transmitting antenna 20 and a receiving antenna 30, and simultaneously performs transmission and reception using electromagnetic waves with a frequency equal to or more than a millimeter wave band. An electromagnetic wave absorber 40 that absorbs electromagnetic waves with frequencies equal to or more than the millimeter wave band is disposed between an arrangement position of the transmitting antenna and an arrangement position of the receiving antenna. An interval D between an antenna element 21 of the transmitting antenna and the electromagnetic wave absorber satisfies a relationship of D>(λ/2π) for a wavelength λ of an electromagnetic wave absorbed by the electromagnetic wave absorber.SELECTED DRAWING: Figure 1
