摘要：
A magnetic coupler arrangement that includes two quarter wave length strip patches, an input signal source, a signal splitter that splits an input signal from the input signal source into two signals and phase-shifts one of the two signals, wherein the phase-shifted signal and the non-phase-shifted signal are fed into the patches of the coupler to achieve a balanced signal configuration.
