Impedance Measurement of Small Antennas Over a Ground Plane Without Direct Cable Attachment

Impedance Measurement of Small Antennas Over a Ground Plane Without Direct Cable Attachment

An indirect impedance measurement approach that does not require direct cable attachment or large space using a two-port network is presented. Using a straight wire monopole as an interrogating antenna and measured impedances of three calibration standards, the input impedance of a small spherical h...
