Figure 1.
Effective area of several generic forms of antenna versus frequency. Dipole (middle curve at lowest frequency), Loop (lowest curve at lowest frequency), ‘Resistive Antenna’ (upper curve at lowest frequency). All formats are assumed to have a linear size of 100 m a conductor diameter of 1mm and an ohmic resistance of 0.021 |$\Omega$| m−1. The resistive antenna parameters were R1=15|$\Omega$| and R2=65|$\Omega$|. The Earth capacitance was assumed to be 700|$\mu$|F.
