| Abstract: | According to the Hugens equivalent principle, the analytical expressions of transient far-zone field radiation for aperture antennas were derived using the method of the direct time domain based on far-zone field approximation in this paper. The radiation features of the main and offset axis were given out. The analysis and numerical results showed that the formulae of the far-zone field were simple and the computation was correct and reliable, which could be used in the design and measurement for the aperture antennas. |
