Dielectric Waveguide Antenna
Abstract
Investigations have continued into developing design criteria for a dielectric waveguide line source antenna. The Marcatili analysis has proven to be a reliable guide for the transmission line design. There is, however, no practical design information available permitting the synthesis of a symmetrical amplitude taper along a grooved dielectric waveguide antenna. This investigation presents a measurement procedure that will permit a correlation between the radiating element physical configuration and the radiation properties. Additional data for various slot geometries will continue to be accumulated. A theoretical and emperical relationship will then be made so as to further relate the slot geometry to radiation characteristics. Our investigations have demonstrated that a non-metallic grooved dielectric waveguide can be made to radiate with a well-formed antenna pattern resulting from an exponential amplitude taper. This effort will be extended to permit the design of a lower sidelobe dielectric waveguide slot antenna.
