Abstract

A review on wideband wide-scanning arrays based on connected slot elements with artificial dielectric superstrates is given. The analysis method to evaluate the active input impedance of the unit cell is described and its application to wideband array designs is discussed. Design examples reaching up to 10:1 bandwidth are presented, including experimental results from prototypes. The typical achieved performance is compared with the state-of-the-art. Aspects such as cross-polarization levels and finite edge effects are also discussed.
