Study of Log Periodic Dipole Antennas

YANG Jun, WU Shi\|cai, GAO Huo\|tao (School of Electronic Information,Wuhan University, Wuhan 430072, Hubei,China)  
Aiming at solving the two problems in the design of LPDA(log periodic dipole antennas), which are how to choose a good calculation method of mutual impedance matrix and improve the radiation pattern at high frequencies, the thesis analyses and compares the calculation methods. A conclusion is drawn that solving Poclinton equation by Galerkin method is the best. A new method through changing LPDA’s structure is presented to improve LPDA’s radiation pattern at high frequencies,and results of computer imitation show it works well. Meanwhile it can enhance the gain at the whole frequencies.
