An optimal design of printed log-periodic antenna for L-band EMC applications

This paper proposes a 12-dipole printed log-periodic dipole array antenna (PLPDA) for L-band electromagnetic compatibility (EMC) applications. The antenna proposed is designed to operate in the frequency range of 0.8 GHz to 2.5 GHz. The proposed antenna design is the result of optimization performed using the Trusted Region Framework (TRF) algorithm. The low values of the S-parameter (S) of the optimized PLPDA antenna design suggest good matching. The antenna also provides satisfactory realized gain between 4.5 dBi to 6.3 dBi along with good directional characteristics in its operating frequency range.
