Without the neutralization line, a decoupling technique for two-element closely-spaced arrays is proposed in this paper. The core component of the proposed scheme is a coupled line section, which can be equivalent to an even-odd-mode impedance transformer. Through the even-/odd-mode analysis, the proposed network is able to simultaneously achieve good impedance matching and isolation.
