Title:
ANTENNA DEVICE, COMMUNICATION DEVICE, AND IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/199966
Kind Code:
A1
Abstract:
Provided is an antenna device that generates or detects electromagnetic waves and includes: a first active antenna including a first oscillator and a first antenna; a second active antenna including a second oscillator and a second antenna; a connecting line connecting the first antenna and the second antenna; a first terminal that receives a signal for controlling a first oscillation frequency of the first oscillator, the first oscillation frequency being prior to synchronization by the connecting line; and a second terminal that receives a signal for controlling, independent from the first oscillation frequency, a second oscillation frequency of the second oscillator, the second oscillation frequency being prior to synchronization by the connecting line.
