The invention relates to a dual-band planar antenna formed by at least one slot of closed shape fabricated on a printed substrate having a perimeter equal to klambda<SUB>f</SUB>, and two supply lines supplying power to the slot via two accesses separated by (2m+1)lambda<SUB>f</SUB>/4, where lambda<SUB>f </SUB>is the guided wavelength in the slot and k and m integers greater than 0, the slot comprising means modifying the operating frequency, one of the supply lines being situated on the said means. The invention is especially applicable to antennas used in domestic wireless networks (IEEE802-11a or Hyperlan 2 standards.
