An antenna resonant and radiant at a predetermined frequency band, comprising:
a dielectric substrate having opposed faces, an electrically-conductive layer serving as a ground plane on one face of the dielectric substrate;
an electrically conductive feed line carried on the opposite face of the dielectric substrate, said feed line having at least one feed end and at least one load end;
and a curved slot formed in said ground plane having a feed side and a load side with respect to said feed end and load end, said slot being electromagnetically coupled to said feed line, such that said slot is resonant and radiant at said predetermined frequency band;
characterized in that said feed line includes a change in width at least at one of said ends thereof to match the impedance of the antenna for said predetermined frequency band. |
