Nature Inspired Golden Spiral Super-Ultra Wideband Microstrip Antenna

This paper presents the design and simulation of a nature inspired fibonacci sequence based golden spiral super-ultra wideband microstrip antenna. The antenna has a compact size of $\pmb{40 \ \text{mm} \ \text{x}40\ \text{mm} \ \text{x}1.6\ \text{mm}}$. Various parameters like return loss $(S_{11})$, radiation pattern, gain and radiation efficiency are analyzed. The impedance bandwidth ranges from 1–35 GHz and bandwidth ratio is 34:1. The proposed antenna is designed, simulated and optimized in HFSS commercial software. Because of the high impedance bandwidth, the antenna can be used in many applications like satellite navigation, GPS navigation, WiFi and high speed technologies like 5G mobile communication.
