Overview

This study presents an optimized dual-band monopole antenna for 5G, Wi-Fi, and UWB, indicating broad bandwidth and high efficiency.

Key Points

  • The antenna achieves resonances at 2.45 GHz and 5.25 GHz with return losses of -28.677 dB and -36.851 dB.
  • It features an impressive impedance bandwidth of 7.564 GHz, effectively covering key frequency ranges for modern applications.
  • Optimized using CST microwave studio, the antenna exhibits omnidirectional radiation patterns and high efficiency values.
  • Significant gains of 2.282 dBi and 4.334 dBi make this design a competitive choice for 5G and Wi-Fi communications.
