Development of a Logo-Periodic Antenna in the Very High Frequency Band and Measurement of its Basic Parameters

In this article, the authors have developed a log-periodic measuring antenna operating in the very high frequency range, and determined its main parameters. Measurements of the parameters of the developed antenna and similar antennas were carried out using the monitoring device and signal generators operating in the range from 350 MHz to 3 GHz, measurements showed that the average sensitivity of the developed antenna in comparison with the other types of antennas and the whip antenna is 15 dBm. When compared with the parameters of the HL-040 antenna, this indicator is practically constant 0.5 dBm in some frequency ranges up to 5 dBm, the developed antenna, by analogy, has a 3 times lower mass, and the geometric dimensions are up to 11 times miniature.
