Design and Performance Analysis of Printed Square Log Periodic Array Microstrip Patch Antenna at 2.5 and 3.5 GHz

This Article defined the design, simulation, edifice and study of inset feed seven elements log periodic microstrip antenna at 2.5-3.5 GHz with the help of Agilent (ADS2009) and Tiny Cad. The antennas were etched/printed on a PCB board using iron on glossy method laser printer and FeCl3, modeled using microstrip lines, the S and 3D parameters data for both shapes were obtained. The data is extracted from the momentum simulation was compared with the measured parameters which were obtained through measurements and simulation. The properties of the square log periodic printed microstrip antennas such as return loss, gain, efficiency, power radiated, cross polarization and the beam width have been investigated and compared. A Square log periodic gain of 3.47dB along with the directivity of 6.99dB, efficiency of 0.74% and resonant frequency of 2.75GHz
