Abstract :
Modal analysis is presented for the realized element gain 
- and 
-plane patterns for a two-dimensional circular cylindrical arrays with concentric dielectric sleeve. Numerical results indicate presence of significant surface wave effects. A design method of dielectric windows to reduce the guided wave effects is proposed. The method, validated by direct evaluation of the element pattern for the optimized window geometries, shows significant reduction of surface wave effects.
