Abstract

In this paper, a flexible 2-port MIMO antenna with dual band-notched properties is designed and built for wireless body area network applications. The antenna's performance in its flat and bent states is measured using liquid crystal polymer as a substrate. Two UWB slot antenna components are arranged parallelly with linked ground. Furthermore, to achieve high port isolation, a decoupling device in the form of a fence is positioned between two antenna units. The measured operating bandwidth can reach 3.0-15.7 GHz, with blocking bands of 5.0-6.5 and 7.0-7.9 GHz. Port isolation (S₂₁) is better than 20 dB. This antenna has fine radiation properties, high isolation, and flexibility, according to the bending and flat antenna tests. It has a promising future for wearable Internet of Things applications.
