| 摘要 |
This differential dipole antenna system (82) comprises, on a same surface of a dielectric substrate, a first half (18) of a thick radiating dipole, a first conducting strip (20) of a bi-strip line for supplying a differential signal, said first conducting strip (20) being connected to the first half (18) of the thick radiating dipole, a second half (28) of a thick radiating dipole and a second conducting strip (30) of the bi-strip supply line, said second conducting strip (30) being connected to the second half (28) of the thick radiating dipole. The system further includes, on said same surface, an additional conducting strip (36) defining a short circuit connecting the first half (18) and the second half (28) of the thick dipole, and a differential resonating filtering device (50) having a bandwidth adapted so as to be combined with the resonance generated by the short circuit (36) so as to generate an antenna impedance matching.
