Abstract
An antenna including a ground plane, a metal plate arranged facing the ground plane, and a supply wire for connecting the plate to a generator or a receiver, such that the antenna has a first resonance frequency in a patch antenna mode. The antenna further includes a ground wire connecting the plate to the ground plane, and a capacitive element arranged in series with the ground wire between the supply wire and the ground plane, such that the antenna also has a second resonance frequency in a wire-plate antenna mode.
