An Unequal Wilkinson Power Divider using Half Mode Substrate Integrated Waveguide

摘要

A new unequal Wilkinson power divider is presented in this paper. The structure benefits from half mode substrate integrated waveguide (HMSIW). In order to increase the characteristic impedance of the HMSIW line, an inductive post is used in the line. Different dividing ratios are obtained by changing the diameter of the inductive post. The experimental results show that the power dividing ratio is 5.1:1 over the frequency range of 9.1 GHz to 12.8 GHz. The input and output ports are well-matched and the output ports are isolated from each other over this frequency range. The experimental results and simulation results of CST Microwave Studio are in good agreement.
