The dual-band reentrant power splitter

A novel configuration of the microwave dual-band power splitter is presented in this paper. The proposed power splitter is based on the reentrant structure in which the metallic body with a floating potential is asymmetrical. As a result, two adjacent work bands are created, leading to quasi-flat maximum responses and that improves the weight, compatibility and cost of the splitter. The general TEM circuit model for the proposed splitter, in terms of a series multi-port connection, is designed and used to determine the initial electrical parameters. An experimental printed unit has been manufactured using conventional printed circuit implementation. The measured S-parameters show an acceptable agreement with analytical and full-wave simulations and that paves the way for a variety of applications.
