Penta Band Circularly Polarized Antenna for Future 6G Applications

In this work we proposed a Penta band circularly polarized antenna for wireless communication applications. The antenna is designed using CST microwave studio using FR4 substrate material. The designed antenna gets stable reflection coefficient in obtained five bands WCDMA Applications <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(1.8 \text{GHz}), \mathrm{S}$</tex> and C band applications <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(3 \text{GHz}$</tex> and 4.3GHz), WLAN applications and satellite communications applications. The antenna is getting stable radiation patterns in obtained frequencies and Antenna is getting efficiency above 80 and front to back ratio of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{7 0}$</tex> percent.
