Abstract:
A printed antenna comprising:(a) a first dielectric layer; (b) a second dielectric layer; (c) a first microwave feed line having a first microwave strip disposed on an outside face of said first layer and having a ground conductor plane disposed between said first layer and second layer; (d) a first radiating element disposed on another face of said second layer and including a plurality of first narrow conductive strips perpendicular to a first coupling slot in said ground conductor plane for coupling said first feed line to said first radiating element; (e) a second microwave feed line constituted by a second microstrip disposed on said outside face of said first layer perpendicularly to said first microstrip and by said ground conductor plane; (f) a third dielectric layer having a face disposed against said first radiating element; and (g) a second radiating element disposed on another face of said third layer and including a plurality of second narrow conductive strips crossing perpendicularly by superposition said first conductive strips ground conductor plane for coupling said second feed line to said second radiating element.
