Abstract

A textile integrated, two-element, multiple-input multiple-output (MIMO) antenna is designed for Wi-Fi, wireless local area network (WLAN), and wearable biomedical applications. A CSRR slot and horn-shaped decoupling structure increases impedance matching and reduces the current movement from one element of antenna to another element which increases the isolation to 7.4 dB. The CSRR slot in the ground is accomplished between the elements to mitigate the surface current and enhance the isolation up to 27.4 dB. The 10-dB radiation exists from 4.65 to 5.97 GHz with more than 20-dB isolation in the full operating band where the maximum isolation is found to be 49.45 dB at 4.7 GHz. MIMO parameters are investigated in a two-element antenna, in which acceptable results are obtained. Bending analysis and phantom analysis are performed for wearable applications which demonstrate the acceptable results.
