Abstract :
Based on the developed theoretical model of the DEDA analysis of its performance and optimization of its structure has been performed. According to simulations the optimized version of the antenna has 50% larger bandwidth, radiates pulse with 1.6 times larger amplitude and has small late-time ringing than the first DEDA antenna.
