Abstract :
Spiral antennas are characterized by low resonant frequencies and broadband matching for high frequencies. We present in this work a theoretical analysis and optimization of a special type of spiral antenna, namely the fractal spiral monopole (FSM). In the low frequencies in the range 0\n\n\t\t
