The Calculation of Spatial Distribution of Electromagnetic Radiation Field Strength in the Near-Field of Medium Wave Broadcasting Antenna
Medium wave broadcasting mainly uses vertically polarized waves to propagate along the ground. The spatial distribution of electromagnetic radiation in the near-field area of the antenna is complicated, which will affect the transmission distance and coverage area of medium wave broadcasting signal. Based on this, the electromagnetic radiation field intensity in the near-field area of the antenna is calculated and analyzed by parameter estimation algorithm to form a numerical representation of the spatial distribution of electromagnetic radiation field intensity. The results show that the radiation power of medium wave antenna and the wavelength of medium wave signal will have different degrees of influence on the spatial distribution of electromagnetic radiation field intensity in the near-field area of antenna, which provides a reference for the research of relevant antenna radiation power.
