Induction vehicle detection and identification system, induction license plate, and induction reader

An induction reader comprising:

• a rectangular magnetic frame placed under the roadway;
• a signal formating and processing node and a matching node, connected to the magnetic frame;
• wherein the magnetic frame forms an HF-band oscillating circuit;
• wherein the magnetic frame is made of conductive material, and wherein the outer perimeter of a cross section the conductive material is 10-100 mm,
• wherein a ratio between a short side of the magnetic frame and a long side is ⅓ to ⅛ of the wavelength, and
• wherein a ratio between a perimeter of the magnetic frame and a wavlength to ⅕ to ½;
• wherein a longer side of the magnetic frame is oriented transverse to the roadway;
• wherein the magnetic frame is placed in a dielectric sheath formed in a substantially parallelepiped shape with a minimum height of 50 mm;
• wherein the magnetic frame placed in a dielectric shell is located at not more than 1 meter deep under the roadway, and
• wherein a dielectric layer separating the magnetic frame from its environment is not less than 50 mm thick.
