Abstract :
A new leaky-wave antenna constructed from a groove non-radiative dielectric (GNRD) waveguide is presented. The GNRD leaky-wave antenna overcomes the difficulty of assembling precisely the dielectric strip in the NRD leaky-wave antenna, and is superior to the NRD leaky-wave antenna of the same size in the radiation pattern. The propa-gation and radiation characteristics of the GNRD leaky-wave antenna are analysed by use of the transverse resonance method. The theoretical results are in good agreement with experimental data.
