Leaky NRD Guide Fed Planar Antennas

摘要

Classical types of leaky nonradiative dielectric waveguide (NRD guide) are described followed by a proposal of a new type of leaky NRD guide based on periodic array of notches created on dielectric strip in the NRD guide. Planar antennas with leaky NRD guide are described with their attractive radiating patterns capable of both linear and circular polarised radiation.
