2x2 Port Super Wide Band Volcano Smoke MIMO Antenna

The Volcano Smoke Antenna (VSA) was introduced in the 1940s by Krauss. However, it was not until the 21st century that this geometry was thoroughly investigated, following the FCC assignment for Ultra Wide Band (UWB) technology. In this conference article, a new Super Wide Band four-port Multiple Input Multiple Output (MIMO) antenna is introduced, utilizing the Volcano Smoke Antenna (VSA) geometry. The antenna, with dimensions of $65\text{mmx}65\text{mm}$, achieves levels below −10 dB for $S11$ and −13 dB for isolation $S1m$ in the band of 2.73-43.38 GHz.
