  author={Xuedao Wang and Jianpeng Wang and Gang Zhang and Jiasheng Hong and Wen Wu},
  journal={IEEE Microwave and Wireless Components Letters},
A new microstrip dual-wideband filtering power divider (FPD) is presented in this letter. The proposed device is mainly composed of a resonator loaded quarter-wavelength (<inline-formula> <tex-math notation="LaTeX">$\lambda $ </tex-math></inline-formula>/4) three-line coupled structure and a modified isolation network. To illustrate the design principle of the proposed FPD, equivalent circuits of the structure under the even-/odd-mode excitations are provided with the derived design equations… CONTINUE READING
