Nowdays the fast and increased demand for bandwidth in the telecommunication world translates into the design of complex boards exchanging data at high bit rate in reduced design cycle. Sometimes it is impossible to spent time in setting pre-layout simulations, because they are not compatible with the design time schedule. In this scenario it is better to design the boards using experience and then make simulations in conjunction with measurements, using customized numerical tools which don't need complex models.

In this work, we have applied a moment-method-based 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-Ω real input impedance at the fundamental resonant frequency. The role of different iteration order for Hilbert antennas, approximately matched to 50-Ω line, on the bandwidth and cross-polarization level of such antennas are investigated numerically. As was shown by Vinoy et al. the radiation patterns resemble those of a linear dipole and for a …
