Abstract :
This paper presents investigations on low-cost arrays printed on reactive impedance substrates. Comparisons of performances are done with similar structures (same materials and thickness) but without a metamaterial lattice. Bandwidth enlarged arrays are designed and considered with various phase excitations. A prototype is manufactured and characterized.
