Abstract

A miniaturized printed log-periodic antenna (LPDA) with lateral size reduced structure is presented. The relative bandwidth of the antenna exceeds 100% when the voltage standing wave ration is less than 2.0. The constructed log- periodic dipole antenna is very useful in the ground penetrating radar due to the very wide bandwidth and relatively small size. The antenna is designed and simulated with the application of CST MICROWAVVE STUDIO software based on the finite integral method. The results show that the radiation characteristic of the antenna designed basically keeps stable over the whole operating frequency band.
