Superdirective Closely-Spaced Arrays
Original language description
In this paper, we employ the concept of source currents to express the directivity of an array in generalized matrix form. It allows finding the excitation currents that maximize directivity for given array. First, we demonstrate this method on an array of two isotropic radiators and express the resulting superdirective currents in closed-form for limiting separation going to zero. Then, using the proposed approach, a superdirective closely-spaced array of two loaded dipoles is designed using full-wave simulator CST Microwave Studio.
