Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059445
Kind Code:
A1
Abstract:
According to the present invention, a first edge of a ground plane extends in a first direction. A radiating element is disposed spaced apart from the ground plane in the thickness direction of the ground plane. A power feed line supplies a high frequency signal to the radiating element. A pair of stubs are disposed in positions sandwiching the radiating element in the first direction. The stubs are connected to the ground plane. In a plan view, the distance, in a second direction perpendicular to the first direction, from the radiating element to the first edge, is at most equal to 1/4 of a wavelength corresponding to the resonant frequency of the radiating element. Beam pattern disturbance can be suppressed even with a configuration in which the radiating element is located close to the edge of the ground plane.
