The purpose of this project is to design and test a novel antenna type known as a Free space Log Periodic Array (FLPDA) in order to enhance directivity within the frequency range of 35 MHz to 60 MHz The two antennas provided eighty percent of the 36 samples when we used the power from before the test. The dipole antenna and the FLPDA were compared statistically with the use of an independent sample T-test. Within the 35-60 MHz range, the novel FLPDA with dipole antenna might be effective. With a directivity of 15.5 dB, the new FLPDA far outperformed the dipole antenna’s 8.5 dB. Thanks to an 80% pre-test power and a p-value below 0.05, the data were considered error-free in SPSS statistical analysis. Two methods for increasing antenna directivity between 35 and 60 MHz were compared and contrasted in this research. The findings demonstrate that compared to the Dipole Antennas, the new FLPDA is much better.
