A single band branch line coupler for butler matrix with semi-lumped element has been proposed in this paper. The coupler is designed to operate properly at 5.8 GHz operating frequency. The capacitors with the value of 33 pF and 4.7 pF are realized as suitable values for lumped element components. I...
