Abstract
(EN)
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.

Un dispositif d'antenne (10) d'un aspect de la présente invention comprend une antenne de résonance d'ordre zéro (20) et une antenne de résonance de premier ordre (30). L'antenne de résonance d'ordre zéro (20) comprend : un plan de masse (5) ; un élément de rayonnement en forme de plaque (21) disposé en regard du plan de masse (5) ; et un conducteur de connexion (23) qui relie le plan de masse (5) et l'élément de rayonnement en forme de plaque (21), et par résonance d'ordre zéro étant effectuée, des ondes électriques d'une première polarisation linéaire sont transmises à toutes les directions orthogonales à cette première polarisation linéaire et/ou reçues de toutes les directions de celle-ci. La première antenne de résonance de premier ordre (30) comprend le plan de masse (5) en commun avec l'antenne de résonance d'ordre zéro, et un premier élément de rayonnement (31) disposé sur la même surface que le plan de masse (5), et par la réalisation d'une résonance de premier ordre, des ondes électriques d'une seconde polarisation linéaire orthogonale à la première polarisation linéaire sont transmises et/ou reçues.
