Title:
ANTENNA, RADIO COMMUNICATION MODULE, AND RADIO COMMUNICATION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2020/090693
Kind Code:
A1
Abstract:
Provided are an antenna, a radio communication module, and radio communication equipment that allow reduction of mutual coupling between antenna elements. 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, in a first direction, at a gap of less than or equal to half of a resonance wavelength. The first radiation conductor and the second radiation conductor are arranged to be shifted in a second direction intersecting with the first direction.
