Title: (EN) ANTENNA DEVICE
Abstract: front page image
(EN)

An antenna device includes a dielectric substrate, a ground plane, an antenna unit, a reflection unit, and an interruption unit. The interruption unit includes a plurality of second conductor patches disposed around the antenna unit, and a plurality of through-holes permitting electrical conduction between each of the second conductor patches and the ground plane, and interrupts a surface current flowing on a surface of the dielectric substrate.
