    Abstract: A Printed Log-Periodic Dipole Antenna (PLPDA) with notched filter at the frequency 2.45 GHz is proposed for wireless communication applications. VSWR <2.5:1 is achieved over the band. The notched filter is achieved by integrating U-shaped slot on the transmission line in order to reduce the interference from the various wireless applications operating at 2.45 GHz frequency. The proposed PLPDA is working from 1-6 GHz frequency with gain >5 dB. The band stop filter is designed with notched frequency band from 2.1-2.6 GHz and integrated with the antenna. Finally, the PLPDA is designed, fabricated and measured. The measured results are in good agreement with simulation results.
