Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/009114
Kind Code:
A1
Abstract:
This antenna device (10) of one aspect of the present disclosure comprises a zeroth-order resonance antenna (20) and a first-order resonance antenna (30). The zeroth-order resonance antenna (20) comprises: a ground plane (5); a plate-shaped radiation element (21) provided facing the ground plane (5); and a connecting conductor (23) that connects the ground plane (5) and the plate-shaped radiation element (21), and through zeroth-order resonance being performed, electric waves of a first linear polarization are transmitted to all directions orthogonal to that first linear polarization and/or received from all directions thereof. The first-order resonance antenna (30) comprises the ground plane (5) in common with the zeroth-order resonance antenna, and a first radiation element (31) provided on the same surface as the ground plane (5), and through first-order resonance being performed, electric waves of a second linear polarization orthogonal to the first linear polarization are transmitted and/or received.
