In this Letter, four differential All‐Pass Networks are presented to introduce phase‐shift at millimetre waves using a linear‐phase synthesis procedure. The proposed networks achieve 1‐3.5 dB insertion loss while having S 11 < − 10dB across the whole bandwidth, showing an almost constant group‐delay, an RMS gain error of less than 0.15 dB and a phase‐error of less than ± 3.5 ° .
