A Dual-Band Branch-Line Coupler with Ultra-Wideband Harmonic Suppression

A Dual-Band Branch-Line Coupler with Ultra-Wideband Harmonic Suppression

A dual-band branch-line coupler with ultra-wideband harmonic suppression is proposed in this paper. The conventional quarter-wavelength transmission lines are replaced with π-shaped lines to achieve a dual band. In addition, ultra-wideband harmonic suppression is obtained by the frequency-selecting...
