چکیده مقاله
In this letter a 3dB miniaturized broadband branch line coupler is designed and experimentally verified The new distributed capacitors which are placed within the empty space of the hybrid, minimize the size of the coupler A prototype at 2 5GHz was designed and built Measurement result confirmed that there is 2700 phase difference between output ports The size of fabricated modified structure shows 55% reduction with respect to conventional 3dB branch line coupler and also the measured bandwidth is 0 5 GHz
