| Abstract: | Operating principle of multi-layered antipodal ultra-wideband(UWB)slot antennas having low cross-polarization characteristics are briefly analyzed first by employing equivalent principle and theory of electrical-magnetic composite dipoles.The feed-line asymmetry's effects on the antennas' impedance matching,cross-polarization and gain,are then investigated by using full-wave electromagnetic simulation.It is shown that the feed-line asymmetry affect the antenna's radiation characteristics within the frequenc... |
