Title:
ANTENNA, WIRELESS COMMUNICATION MODULE, AND WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/090692
Kind Code:
A1
Abstract:
Provided is an antenna comprising: a first antenna element comprising a first radiation conductor and a first power supply line; a second antenna element comprising a second radiation conductor and a second power supply line; a first coupling body; and a first coupling part. Each of the first antenna element and the second antenna element is configured to resonate respectively at a first frequency band and a second frequency band. The second power supply line is configured to be coupled to the first power supply line with primacy given to a first component of any of a capacitance component and an inductance component. The first coupling body is configured to couple the first power supply line with the second power supply line with primacy given to a second component which differs from the first component. The first radiation conductor and the second radiation conductor are arranged at a spacing which is half or less of the resonant wavelength. The second power supply line is configured to be coupled to the first radiation conductor with primacy given to a third component of any of the capacitance component and the inductance component. The first coupling part is configured to couple the first radiation conductor with the second power supply line with primacy given to a fourth component which differs from the third component.
