Abstract

A recently proposed concept of a self-oscillating non-Foster antenna is extended to a Huygens radiator. The system is comprised of two orthogonal pairs of electric and magnetic near-field parasitic radiators, each of which is driven by a small electric dipole. The input ports of the driving dipoles are connected to a floating negative impedance converter, thus forming a broadly-tunable and nearly perfectly matched self-oscillating system. The developed concept is verified with a series of full-wave/circuit theory (CST/ADS) co-simulations. Obtained results reveal self-oscillations that can be tuned within a 1: 1.5 frequency range, with familiar cardioid radiation patterns.
