The application of Hallen equation in antenna is analyzed based on MATLAB

In this paper, the basic thinking of analyzing antenna by moment method is briefly discussed, and the mathematical expressions of Hallen integral equation in the application of symmetric oscillator antenna and Yaki antenna are derived in detail. Hallen integral equation, two-position equation and Pocklington integral equation were analyzed and compared by using a half-wave symmetric oscillator [1]. Based on Hallen equation, current distribution, input impedance, power gain and other parameters of two typical antennas (symmetrical antenna and Yagu antenna) are calculated by MATLAB, 2d and 3D directional graphs are drawn, and the performance of different length oscillator antennas is studied. Finally, the analytical results are compared to illustrate its correctness.
