Abstract

This article presents a unique meta-inspired decoupling method to reduce the isolation in a multi-band MIMO antenna. The proposed textile-based antenna is designed to cover the frequency spectra of IEEE 802.11a and b/g/n (2.4–2.484 GHz and 5.15–5.85 GHz) WLAN applications. The isolation improvement in multiple WLAN frequencies are achieved by a modified SRR meta-inspired structure without upsetting the parameters of the MIMO antenna. The maximum isolation improvement of around 10 dB is obtained at 2.4 GHz (S21 < −18 dB), 20 dB at 5.2 GHz (S21 < −38 dB) and 10 dB at 5.8 GHz (S21 < −34 dB). The antenna fulfills the dual wideband frequency spectra from 1.34 to 3.92 GHz (56%) and 4.34–6.34 GHz (37.4%). The proposed prototype is fabricated on a jean’s substrate with the dimension of 100 × 60 × 1 mm3 while a single element occupies the size of 60 × 60 × 1 mm3. The gap between two antenna element is 0.1 λ0. The measured peak gain in two bands are found around 3 dBi and 5 dBi at 2.4 GHz and 5.8 GHz respectively. The ECC and DG are found around < 0.04 and > 9 respectively over the desired bands. The measured results show a good agreement with the simulated one.
