Title:
ANTENNA, RADIO COMMUNICATION MODULE, AND RADIO COMMUNICATION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2020/090691
Kind Code:
A1
Abstract:
This antenna has a first antenna element, a second antenna element, a first coupling body, and a second coupling body. The first antenna element includes a first radiation conductor and a first feeder line, and is configured to resonate in a first frequency band. The second antenna element includes a second radiation conductor and a second feeder line, and is configured to resonate in a second frequency band. The second feeder line is configured to be coupled to the first feeder line such that a first component that is one of a capacitance component and an inductance component is predominant. The first coupling body is configured to couple the first feeder line and the second feeder line such that a second component different from the first component is predominant. The first radiation conductor and the second radiation conductor are arranged at a gap of less than or equal to half of a resonance wavelength. The second radiation conductor is configured to be coupled to the first radiation conductor in a first coupling mode in which one of capacitive coupling and magnetic field coupling is predominant. The second coupling body is configured to couple the first radiation conductor and the second radiation conductor in a second coupling mode different from the first coupling mode.
