Document Type and Number:
WIPO Patent Application WO/2018/198981
Kind Code:
A1
Abstract:
[Problem] To provide an antenna with which directionality in a specific direction can be obtained without a balun.
[Solution] An antenna provided with: a ground plane; a first resonator connected to a feeding point having the ground plane as a reference; a second resonator which is contactlessly fed by means of the first resonator via electromagnetic field coupling or magnetic field coupling; and at least one waveguide spaced apart from the first resonator and the second resonator. The ground plane is disposed on the opposite side from the waveguide with respect to the second resonator and used as a reflector. Alternatively, the antenna is provided with a reflector positioned on the opposite side from the waveguide with respect to the second resonator.
