A leaky coaxial cable antenna based on sinusoidally-modulated reactance surface

This paper presents the simulated results of a leaky coaxial cable antenna (LCXA) based on sinusoidally modulated reactance surface (SMRS). The theory of SMRS is employed to transform the leaky coaxial cable (LCX), a uniformly radiating structure into a directional antenna, LCXA. It is shown that high gain and arbitrary direction of radiation could be achieved by LCXA.
