A MIMO antenna designed for use in wearable case with four ports and ultra-wideband (UWB) technology has been created. The design element is equipped with a circular patch that provides improved impedance matching across the ultra-wideband spectrum, eliminating the need for a feeding line. The circular shape is cut to place the four-antenna elements around the edges of the square ground. The MIMO antenna provides an improved S11 reflection coefficient for impedance matching, increased isolation among ports (S12, S13, S14), and varying radiation pattern features.

摘要

A MIMO antenna designed for use in wearable case with four ports and ultra-wideband (UWB) technology has been created. The design element is equipped with a circular patch that provides improved impedance matching across the ultra-wideband spectrum, eliminating the need for a feeding line. The circular shape is cut to place the four-antenna elements around the edges of the square ground. The MIMO antenna provides an improved S11 reflection coefficient for impedance matching, increased isolation among ports (S12, S13, S14), and varying radiation pattern features.
