Summary:
A novel four-way power divider based on substrate integrated waveguide is presented. Broadband performance is obtained by using a stepped coaxial line transformer together with tapered substrate integrated waveguides. Simulated and measured results show that good performance of insertion loss and impedance matching is achieved over a broad bandwidth from 4 GHz to 11 GHz. When the proposed power divider is applied for active antenna array, it can be shown that by using appropriate matching networks, gain fluctuation caused by nonideal return loss and isolation can be alleviated.
