Title:
RADIO COMMUNICATION DEVICE
Document Type and Number:
Japanese Patent JP2023122285
Kind Code:
A
Abstract:
To achieve both acceleration of data transmission and a reduction in height of a radio communication device.SOLUTION: A radio communication device has a first antenna for performing radio communication by electromagnetic field coupling, and communication control means for transmitting or receiving signals in the first antenna. The first antenna includes a first conductor that has a shape along an arc shape centered on a predetermined axis, and a second conductor that is arranged on the inside of the first conductor with respect to the predetermined axis in a viewpoint in a reference direction parallel to the predetermined axis, and has a shape along an arc shape centered on the predetermined axis. A second signal fed to one end of the second conductor is fed with a predetermined amount of delay from a first signal fed to one end of the first conductor.SELECTED DRAWING: Figure 1
