Abstract :
A compact ultra-wideband quasi log-periodic dipole antenna (LPDA) printed on dielectric substrate is proposed in this paper. The antenna is realized by cascading straight line LPDA with 29 elements and meander line LPDA with 11 elements. An ultra-wideband of 20-2200 MHz was obtained, and the antenna gain was about 6 dBi in the band of 100-2200 MHz. The simulation results indicate that the designed UWB LPDA has very stable radiation patterns throughout the whole frequency band combined with low profile and ease fabrication, which show great potential for VHF and UHF bands wireless communications.
