Overview

An optimized MIMO antenna shows a 125% impedance bandwidth in wireless applications, highlighting effective band-rejection.

Key Points

  • The antenna achieves an impedance bandwidth of −10 dB from 2.7 to 11.67 GHz, covering a wide frequency range for various applications.
  • It includes penta-notched filtering capabilities across five specific frequency ranges to suppress unwanted signals effectively.
  • The innovative design features cross-shaped extensions for improved isolation, achieving an isolation level greater than 20 dB.
  • With envelope correlation coefficients below 0.04, the antenna supports high performance in MIMO communication configurations.
