In this paper, different methods for measuring the input ( ) impedance of a quadrifilar helix QFH antenna are presented along with the underlying physical theory. Shortcomings of the known slotted line method are discussed. New practical and efficient ways of the input impedance deri¨ation based on
Traditional impedance measurement of a monopole antenna is inaccurate due to a likely stray radiating current on the measuring cable that is also affected by the operating human. This letter demonstrates experimentally that the elimination of this stray current is possible by using a special slee¨e
