Design of Microstrip Leaky Wave Antenna Composed of Composite Right/Left Handed Transmission Line

leaky-wave antenna; composite right/left-handed transmission line; scanning beam; radiation characteristic

In this paper, by referring to the new equivalent model, I designed and made three kinds of antenna objects of composite right/left-handed transmission line with microstrip leaky-wave antenna. By using network analyzer, I measure their S parameter and the result showed that the physical model, circuit model and antenna object all have good consistency. In order to make further study on the characters of space scanning beam on composite right/left-handed transmission line, I simulate the far field radiation characteristics for above three antenna objects and he made the object test in the anechoic chamber. I drew such conclusion: under the equilibrium state, composite right/left-handed transmission line with microstrip leaky-wave antenna has more even radiation characteristic above different beams.
