Analysis of Radiation Patterns of Log-Periodic Dipole Array Using Transmission Line Matrix Model

Surender Daasari, Suresh Thallapelli

The introduction of broadband systems to communication and radar technologies has demanded the design of broadband antennas. In this thesis, A broadband log-periodic dipole array antenna using Transmission Line Matrix Model is investigated. A log-periodic dipole antenna is analyzed using Transmission Line Matrix Model within the frequency band of 0.5 GHz-6 GHz. After the simulations made with MATLAB, a prototype single polarized LPDA antenna is produced. Developments on the prototype antenna are performed, both to improve the electrical characteristics of the antenna and to make the final design realizable. Results which are obtained in MATLAB are compared with results obtained by designing Log-Periodic antenna using PCAAD.
