Abstract
A differential dipole antenna system includes, on a same surface of a dielectric substrate, a first half of a thick radiating dipole, a first conducting strip of a bi-strip line for supplying a differential signal, the first conducting strip being connected to the first half of the thick radiating dipole, a second half of a thick radiating dipole and a second conducting strip of the bi-strip supply line, the second conducting strip being connected to the second half of the thick radiating dipole. The system further includes, on the same surface, an additional conducting strip defining a short circuit connecting the first half and the second half of the thick dipole, and a differential resonating filtering device having a bandwidth adapted so as to be combined with the resonance generated by the short circuit so as to generate an antenna impedance matching.
