Network Type Impedances at Single Points on Conductors: Application to Wire Antennas

The transition from impedances in networks, where there are always two terminals present, to the field impedance at a single point in a medium demands a certain degree of maturity for full understanding. An intermediate step in the transition is considered by defining the impedance at a single point on a conductor in network terms. The introduction of this new impedance is applied to the operation of loaded wire antennas and results in greater ease of analysis and a readier understanding of the effect of changes in the antenna dimensions and loading.
