| Abstract | A tunable microstrip dual-band branch-line coupler using defected ground structure (DGS) stub tapped branch line is presented in this paper. Tuning the geometrical parameters of the DGS, both characteristic impedance and electrical length of an open stub can be controlled. To verify the frequency agility, a prototype dual-band coupler operated at 0.8 GHz and 1.9 GHz with 100 MHz frequency tuning range is fabricated and measured. In the frequency tuning range, the overall small phase and amplitude errors are also observed respectively. |
