Abstract

Multi-antenna satellite navigation receivers provide recision and robustness against multipath propagation and in-band interferers. However, with the prerequisite of compactness, the radiation efficiency of the array is limited by the strong mutual coupling between its elements. Decoupling and matching networks (DMN) are used to mitigate the coupling and thus enhance the high-order eigenmode radiation efficiencies of the array. Nevertheless, this limitation of efficiency motivates to exploit further sources of diversity and therefore a dual-band dual-polarized ompact antenna array with a decoupling and matching network is proposed. The compactness and integration of the receiver are improved by designing the network on a multilayer printed circuit board attached directly to the antenna. The decoupling elements are designed in stripline technology and the matching circuits are designed using lumped elements.
