Abstract

A dielectric leaky-wave antenna with a new perturbation scheme is developed. The attenuation constant with different gap width between metal patches is determined experimentally. The dielectric waveguide used is an anisotropic sapphire rod. The conventional effective dielectric constant (EDC) method is modified to calculate the unperturbed propagation constant and then used to predict the main beam position. The experimental data agree quite well with that of the simulation
