An Optimization Design Method for Dual-Band and Wideband Patch Filtering Power Dividers

Abstract

This paper proposes a new automatic design method based on continuous and binary optimization for dual-band and wideband filtering power dividers (FPDs). The designs utilize an optimization process to manipulate the multiple modes of a patch radiator. In this way, both dual-band and wideband operations can be achieved. Meanwhile, the filtering property is also taken into consideration during the optimization, which finally produces power dividers with filtering functions. The design process is highly automatic to minimize manual calculations and simulations. Finally, a dual-band filtering power divider whose center frequencies are 2.4 GHz and 6 GHz and a wideband filtering power divider operating from 3.7 GHz to 5.25 GHz are designed and fabricated for validation.
