Abstract :
An indirect impedance measurement approach that does not require direct cable attachment using a two-port network is designed and numerically evaluated. Using a monopole as an interrogating antenna, the impedance of a small spherical helix dipole over a ground plane is retrieved. The accuracy and sources of error are discussed.
