In this paper, analysis of dipole antenna array with each element loaded with an active device (i.e., two-terminal oscillator) is presented. The analysis is equivalent to solving a multiport network circuit with each port shunt with a two-terminal oscillator and an equivalent exciting source. A characteristic equation with the order of 2N is derived to describe the stability condition of a N-element injection-locked active antenna array. The Routh-Hurwitz stability criterion is then applied to remove the unstable solutions. Numerical results show that the array performance such as frequency locking range by taking into the array mutual coupling effect is quite different from that of an isolated antenna element.
