Ultra Wide Band LPDA Design using HFSS

In this paper, the authors describe the development of LPDA using HFSS. Log periodic antennas are antennas with high gain, large bandwidth, large front to back ratio and low cost. These antennas are quite convenient for commercial broadcast and radio signal detection. The UWB LPDA antenna is slightly modified to cover 1GHz to 4GHz bandwidth. The radiation patterns of sum and differential modes show good gain and null depth in the end-fire direction, respectively. The performance of the designed antenna is verified by finite integration and finite element method comparisons. The design of LPDA is reduced to attain better impedance matching.
