Abstract :
A wide-band antenna element with an integrated balun has been successfully developed. This element will be used in the OSMA demonstrator array. The measured and predicted bandwidth of an isolated balun is 4:1 for a return loss lower than -18 dB (VSWR 1.3:1). For an antenna element with integrated balun a VSWR of 2:1 is achieved over an octave bandwidth. A VSWR< 2.7:1 was measured over a frequency band of 4:1.
