Abstract :
A reconfigurable output power 4×4 Butler matrix consisted of four adjustable output power ratio branch line couplers and two 45 degree phase shifters is proposed. The adjustable output power ratio branch line coupler is accomplished by simply changing the values of two shunted capacitors. The simulated antenna factors of four different inputs changes as predication are also presented.
