Abstract
The invention relates to a planar antenna realised on a substrate comprising a slot of closed form dimensioned to operate at a given frequency in a short-circuit plane of at least one feed-line. The perimeter of the slot being designed such that p=kλs where k is a whole number greater than 1 and λs the guided wavelength in the slot, the antenna comprising at least one first feed-line placed in an open circuit zone of the slot and a second feed-line placed at a distance d=(2n+1)λs/4 from the first line, where n is an integer greater than or equal to zero.
