Abstract :
A new type of foam is proposed as a basic substrate for printed arrays operating in the X-band and above. As an example, 2×2 and 4×4 circularly polarised (CP) microstrip arrays are designed at 11 GHz showing an axial ratio (AR) bandwidth greater than 10% with excellent gain and return loss performances
