A Microwave Network Interconnected by Flexible Printed Board

Multi-layer microwave printed board technology has been evolving rapidly with advances in microwave integrated feed network, which leads to increasingly complex and variable spatial structures of microwave networks. This paper proposes a new method to connect microwave interconnection networks using flexible printed boards. The multilayer boards can be installed at any angle by bending the flexible board, which can make full use of the system's space to achieve conformal requirements. The microwave network realizes the distribution, synthesis and monitoring functions of the main 9-channel signals. The measured results are in good agreement with the simulations, which proves that the method is feasible.
