Input impedance of a chirostrip antenna L Vegni and A Toscano Third University of Rome, Department of Electronic Engineering, Italy Abstract A very efficient yet rigorous method is presented for the analysis of chirostrip antennas embedded in a substrate above an infinite ground plane. The method is based on the well known spectral domain moment method and can be used for the analysis of single
