A Wideband Balun — How Does it WorkA Wideband Balun ― How Does it Work?
Antennas often require a balanced feed system like the circuit described in this article

By J. Thaysen, K. B. Jakobsen and J. Appel-Hansen Technical University of Denmark
henever a balanced antenna (i.e., dipole, loop or spiral) is used, the issue of how to feed the antenna becomes relevant. Because a balanced antenna requires a balanced feed, a balun is needed. A balanced antenna fed by a two-wire transmission line is a balanced system with respect to L Figure 1. Balun for use with a spiral antenna. the lines, provided that the two feed points on the balanced antenna have the same orientation and place- makes it realizable using conventional photo ment with respect to the lines. If the balanced techniques. (symmetrical) antenna is connected to a coaxi……
