Abstract In this paper, a kind of linear-end metallic thin wire antenna is studied. The properties of the transmitted waveforms in free space, the footprints and the VSWR are simulated with the FDTD method and tested. Simulations are carried out for various parameters such as end resistor values, permittivity values, flare angles, and height above the ground. The electronic field distributions in near field are simulated in different modulated frequencies. The results show that the simulation results and the measurement results are basic agreement. The results also show that this kind of antenna is more adaptive to the different working conditions than the common bow-tie antenna.
