Patent ID: 7362273

Claim:
An antenna apparatus for the reception of, and or transmission of, electromagnetic energy, the apparatus comprising: a non-radiating dielectric waveguide, the non-radiating dielectric waveguide further comprising a first conductive plate and a second conductive plate arranged substantially parallel to each other at a predetermined distance, and a dielectric strip element having a length direction positioned between the first conductive plate and the second conductive plate; a first aperture fabricated on the first conductive plate and aligned with the dielectric strip element; a second aperture fabricated on the second conductive plate, aligned with the dielectric strip element and positioned at a proximate end of the second conductive plate; a third aperture fabricated on the second conductive plate, aligned with the dielectric strip element and positioned at a distal end of the second conductive plate; an antenna element aperture coupled to the first aperture; and a first transmission line element electromagnetically coupled to the second aperture and a second transmission line element electromagnetically coupled to the third aperture, the first transmission line element and the second transmission line element positioned to be substantially orthogonal with each other.
