SUMMARY
In this research, Yagi antenna and printed Yagi antenna as one of the components of lightning detection sensors have been designed and simulated. Both antennas have the same number of elements and are fed by the coaxial probe technique. Printed Yagi antennas use a dielectric substrate with a certain relative permittivity as a medium, while the conventional one uses air as a medium. The final dimension of the Yagi antenna is 0.84? x 0.5?, while the printed Yagi antenna is 0.595? x 0.47?. The simulation results show that with a smaller, lighter, and compact size, printed Yagi antenna is able to work at the same frequency as conventional Yagi antenna with a reflection coefficient of -17.1dB, the peak gain of 8.8dBi, and has a directional radiation pattern in the VHF-band.
