Title:
A multiband antenna and radio equipment
Document Type and Number:
Japanese Patent JP6233319
Kind Code:
B2
Abstract:
A multiband antenna includes a feeding element connected to a feeding point, a radiating element functioning as a radiating conductor, the radiating element being positioned apart from the feeding element and fed with electric power by electromagnetically coupling to the feeding element, a ground plane, and a non-feeding element being positioned close to the radiating element and connected to the ground plane via a reactance element. The reactance element has a reactance that causes the multiband antenna to match with a frequency other than a resonance frequency of a resonance mode of the radiating element.
