Abstract: This talk mainly covers a new thought to integrate the feeding networks of multiple phased arrays. With multi-operational modes (abbreviated as multimode hereafter) synthesized transmission lines, the feeding networks of several phased arrays with various functionalities could be integrated together without using active switches. The multi-mode line functions equivalent to its conventional counterpart with a specific characteristic impedance and electrical length in one of the given bands, but resembles an open or short circuit in the others. With the aid of synthesized lines, the direction of signal flows in the feeding network can be controlled with high degrees of freedom, and hence fulfill the design goal. As a proof of the concept, three heterogeneous integrated phased arrays, eventually could serve as the RF front-end in future UAV applications, are developed and introduced.
