Abstract

A low-profile Octal element Ultra-Wideband (UWB) Multiple-Input–Multiple-Output (MIMO) antenna based on a clamp structure designed for deployment within an intelligent digital entertainment network leveraging Internet of Things (IoT) technology is presented in this article. The single element antenna can operate over the UWB frequency band, i.e., from 3.1–10.6 GHz, accomplished by placing an extended stub on the ground. The octal antenna comprises eight monopole Antenna Elements (AEs) with clamp-shaped radiators and connected ground structures. The AEs are orthogonally oriented, and the Spiral-shaped Connected Ground Structure (SCGS) provides isolation greater than 20 dB. The results show that the antenna has an Envelope Correlation Coefficient (ECC) and a Channel Capacity Loss (CCL) less than 0.02 and 0.3 bps/Hz and a Diversity Gain (DG) greater than 9.9 dB. Dual, quad and octal port antennas are simulated and fabricated to analyze the MIMO parameters with same ground structures. So, it has the potential to be scaled up to 64 elements or more by adopting the same ground structure.
