Abstract :
A compact digital phase shifter is presented utilising negative phase velocity in metamaterial technology. The phase shifter was designed and it was measured ranging from 0deg to 360deg with discrete increments of 60deg. The measurement result shows that the average increment of phase shift was X = 59.28deg and its standard deviation was sigma = 6.64deg.
