Claim:
1. Method for realizing a slot antenna in a multilayer substrate of a printed circuit comprising at least a first conductive layer, a dielectric layer and a second conductive layer, the method comprising: etching in the edge of the first conductive layer a short-circuited slot-line having an electrical length L, etching in the first conductive layer a slot surrounding the slot-line and an opening at the short-circuited part of the slot-line so as to realize, a first portion of a first conductive band having an electrical length L and a second portion of said first conductive band having an electrical length L etching in the second conductive layer, of a second conductive band in the form of a loop having an electrical length L one end of the second conductive band being connected to the first portion of the first conductive band and the other end of the second conductive band being connected to the second portion of the first conductive band so as to form a conductive loop wherein the sum of the electrical lengths L
