Research on the calculation methods of electromagnetic radiation field based on half-wave antenna

This paper mainly researched a kind of calculation method to the electromagnetic radiation of the transmitting antenna, in order to adapt to the needs of the environment and military operations. The paper was based on the delayed bit and the vector-bit to derive the distribution of electromagnetic radiation field for symmetric oscillator in the ideal space, and the distribution of electromagnetic radiation field for the typical half-wave antenna by the superimposition of differential current. It implemented the calculation method of the propagation of electromagnetic wave radiation field for the symmetric oscillator and the half-wave antenna in the ideal space, and summed up the features of electromagnetic waves in the far field (radiation area). This electromagnetic radiation field in the paper is calculated with the high reliability characteristic. It can be very important reference value in practical applications.
