Analysis of Sun Flower Shaped Monopole Antenna

The theoretical analysis of nature inspired antenna along with measured results of fabricated prototype is presented in this work. The space between successive antenna elements in form of spirals behaves as a leakage cavity which represents incident wave’s amplitude increases by existence of seed’s cavity. Our antenna design converts incident signal into high strength signal in term of amplitude which is major requirement in satellite communication system. The proposed design has low profile and improved noise figure which enhance its suitability in satellite communication. The measured results are also found to be in concurrence with simulated results.
