What might have happened if antenna theory had taken another path, one that led to simplification instead of increasing mathematical sophistication? This column will explore one such “what if”. The example comes from the world of wire antennas; however, thanks to the Theory of Complementary Antennas, it also embraces small apertures. No doubt, such stories can be told about the world of large apertures as well.

Some methods of antenna modeling and measurement lead directly to radiation patterns and total radiated power without the intermediate, and often tedious or impractical, step of calculating self and mutual impedances. 1 Still, it is often desirable and necessary to know the input impedance for each element in the...
