Dispersion and interaction impedance of two kinds of vane-loaded helical SWS were measured in 2～18 GHz with Agilent8510C Vector Network Analyzer. The measurement system was represented by proper microwave network and a formula to modify phase shift of SWS was derived that took reflection effects of transmission ports into account. Thus the fluctuation of experiment values were damped effectively. Dispersion and interaction impedance of them were also simulated by HFSS with space-harmonics effects included and ignored respectively. The experimental and theoretical values of dispersion and interaction impedance are found to be close in the band of 2～18 GHz.
