Two experimental versions of feeding systems for broadband antennas are described in this paper. Tapered transmission lines are used in the design of one, and the conventional type of baluns in the second. These feeding systems are employed to feed four‐arm sinuous antennas in order to allow good impedance matching and good electrical characteristics over more than one octave. Experimental results of input impedance and radiation patterns are also given. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 195–200, 1999.
