A Low Cost, Mm wave Waveguide-To-Strip line Transition For 5G Applications

In millimeter-wave systems, a waveguide to stripline (SL) transition is a key passive component that connects RFICs and other components. This manuscript presents a novel low-cost, mm-Wave waveguide-to-strip line transition using a circular resonating element. Owing to the compactness of structure, it can be easily deployed in 5G applications. The proposed structure is simple, robust, and easy to fabricate with good performance. The transition achieves an impedance bandwidth of 10.4 G from 27.45 GHz to 30.47 GHz.
