Abstract

This paper presents a compact ultra-wideband (UWB) antenna fed by strip line. The antenna is a log-periodic dipole antenna with 18 elements. Simulation by Ansoft High Frequency Structure Simulator (HFSS) 10.0, the in-band impedances are quite stable and satisfactory. A rejected narrow frequency band is further obtained within the wideband width by inserting an H-shaped slot into the central fed line of the antenna. The antenna has a dimension of 47.8mm by 42 mm by 2mm. The simulation results show that the proposed antenna has stable directional radiation patterns, very low-profile and low fabrication cost, which are suitable for UWB system.
