Abstract:

A number of self-complementary structures are investigated with the goal of providing frequency-independent matching of the inductive reactance of the other element. Impedance bandwidths of up to 501 are found to be achievable with very small H approximately 0.006 lambda element heights. Efficiencies are determined by achievable loss resistances in the radiating structure itself, rather than the limited quality of an external loading coil, and by energy channeled into the difference port of the feed hybrid, which is used to match two complementary impedances.
