Abstract
A new way to calculate the complex propagation constant, γ=α+jβ, of a microstrip leaky wave antenna (MLWA) is presented. The calculated normalized complex propagation constant fits well with the comparison data. The properties of the leaky wave antenna in the first high mode are discussed using the simple cavity theory. It is explained, in principle, why the MLWA has a leaky region and critical frequency. Some simple rules about how to choose the width and permittivity of the MLWA are given.
