Sinusoidally Modulated Reactance Surface Loaded Leaky Coaxial Cable

In this paper, the theory of sinusoidally modulated reactance surface (SMRS) is employed to enhance the radiation efficiency of leaky coaxial cable (LCX). The LCX's slots are loaded by a periodically etched dielectric stripe, partially converting the bounded monofilar mode into a radiating mode. The simulated results are discussed and it is shown that the coupling loss can be significantly decreased by SMRS loading, which increases the indoor coverage capability of the LCX.
