Abstract

Abstract

In this paper, one design method of decoupling wideband antenna array based on multi-route decoupling network is proposed. At the beginning, the decoupling and matching conditions of the common multi-route decoupling network model are derived by employing node analysis, and the general design process is obtained. Then, the proposed decoupling network is applied to a two-element antipodal Vivaldi array, and its dimensional parameters are achieved via the designing basis at low band and the design process. Also, gradient transmission lines are added to extend the decoupling bandwidth. The measured results indicate that the isolation is higher than 20 dB in the operation band of 3.34～13 GHz (3.89:1), which is 58.8% wider than that of the coupled array. Finally, the decoupling effectiveness is further verified in one-dimensional eight-element array, and in-band isolation is always higher than 20 dB. Moreover, the array owns good radiation performance in the scanning range of ±60°. The presented multi-route decoupling network features generality, simple structure and wideband decoupling performance, and is potential in the application of phased arrays and large-scale communication systems.
