Abstract―In this work, we have applied a moment-methodbased simulation code to perform a detailed parametric study of the bandwidth, cross-polarization level, and the feed location characteristics of the matched Hilbert antenna. It is shown that a properly chosen off-center near-the-end feed point may provide an approximate 50- real input impedance at the fundamental resonant frequency. The role of different iteration order for Hilbert antennas, approximately matched to 50- line, on the bandwidth and cross-polarization level of such antennas are investigated
