Document Type and Number:
WIPO Patent Application WO/2020/240916
Kind Code:
A1
Abstract:
A multiband antenna (1) according to the invention is provided with: a board (40); an input terminal (16) to which signals are input; a conductive antenna part (10) connected to the input terminal (16) and having, in the order from the input terminal (16) side, a first low-inductance part (11), a first high-inductance part (12) in a meandering form, and a first front part (13) that are connected in series; and a conductive ground part (20) isolated from the input terminal (16) and having, in the order from the input terminal (16) side, a second low-inductance part (21), a second high-inductance part (22) in a meandering form, and a second front part (23) that are connected in series, wherein the electric length of the first low-inductance part (11) is one quarter-wavelength of a first frequency and wherein the sum of the electric lengths of the first low-inductance part (11), the first high-inductance part (12) and the first front part (13) is one quarter-wavelength of a second frequency.
