Delta antenna is a typical antenna for ionospheric vertical detection, and its radiation performance is mainly determined by the length and obliquity of the basic elements. To obtain better radiation characteristics an optimization method for designing Delta antenna is proposed, and the method is based on simulated annealing (SA) and the basic frequency method. The measured results using an optimized antenna at 1-30 MHz show that the optimization is fast and effective.
