The invention relates to capacitive-coupling grounding transmission devices (200, 300 and 400) and phase shifter network equipment. Each capacitive-coupling grounding transmission device comprises a stripline cover (2), a stripline substrate (12) and a coupling block (8), wherein the coupling block (8) is arranged between the stripline cover (2) and the stripline substrate (12); and the stripline cover (2) and the coupling block (8), and the stripline substrate (12) and the coupling block (8) are coupled in a capacitive coupling manner respectively. An appropriate capacitive coupling surface can balance a current between an inner cable and an outer braided cable, so that the same good voltage standing wave ratio and phase performance as those of traditional equipment can be achieved.
