Synthesis and Realizability in Design of Minimum-Simulation Inline Antenna Arrays

This article discusses a simplified design technique of antenna arrays. The technique relies on a single electromagnetic simulation of an arbitrary inline core element, for instance, a printed patch antenna or a waveguide slot, and several identical core elements are then cascaded by means of transmission lines with given length and characteristic impedance. Realizability constraints as well as extended possibilities are discussed. Design examples are presented and characterized for validation.
