Title:
TRANSMISSION DEVICE AND TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/105983
Kind Code:
A1
Abstract:
This transmission device comprises: an array antenna (21) having a plurality of reception antenna elements (22) and a plurality of transmission antenna elements (23); and a plurality of phase conjugate circuits (40) connected to the reception antenna elements (22) and the transmission antenna elements (23). The frequency of a transmission signal outputted from each of the phase conjugate circuits (40) is equal to 1/2 of the frequency of a pilot signal inputted to the phase conjugate circuit (40). The phase difference between the transmission signal outputted from each of the phase conjugate circuits (40) and a transmission signal outputted from a given one phase conjugate circuit (40), among the phase conjugate circuits (40), is equal to -1/2 of the phase difference between the pilot signal inputted to each of the phase conjugate circuits (40) and a pilot signal inputted to the given one phase conjugate circuit (40).
