Simulation and Analysis of Multi-layered Balanced Antipodal Ultra-wideband (UWB) Slot Antennas
摘要
Abstract
Operating principle of multi-layered balanced antipodal ultra-wideband (UWB) slot antennas having low cross-polarization characteristics are analyzed first by employing equivalent principle and theory of electrical-magnetic composite dipoles.The effects of the tuning stubs' shapes on the antennas' impedance matching,cross-polarization and gain are then investigated by using full-wave electromagnetic simulator.It is shown that the tuning stubs' shapes affect the antennas' return loss more significantly than the antennas' radiation characteristics within the frequency range.These results should be useful for the optimization design of UWB balanced antipodal slot antennas having low cross-polarization characteristics.关键词
