The Design of Image Transition of Novel Half Mode Substrate Integrated Waveguide

This paper investigates the design of image transition junction of half mode substrate integrated waveguide(HMSIW)and its potential application in the design of power splitter.Firstly,the limitation of applying HMSIW to design power splitter is revealed and then an image transition of HMSIW(ITHMSIW)is proposed followed by the introduction of the design principle.With simulation and experimental analysis,the feasibility of HMSIW equipped with image transition is validated in comparison with HMSIW.After that,an HMSIW crisscross three-way power splitter with image transition junction is designed and tested.The corresponding results illustrate that the HMSIW image transition proposed has good performance and can effectively extend the application areas for HMSIW in microwave and millimeter-wave power splitter design.
