Abstract

In this paper, a compact UWB MIMO antenna with enhanced isolation for WBAN applications is proposed. The proposed antenna consists of two folded antenna elements, a ground plane, and a T-shaped isolator. The overall dimension is 26 mm × 26 mm × 5 mm. In order to enhance the isolation between the two antenna elements (S₂₁), the T-shaped isolator is placed between antenna elements. Simulated results show that the proposed antenna on a human equivalent phantom has the 10-dB return loss bandwidth of 5.8 GHz ranging from 3.0 to 8.8 GHz, the isolation of less than -12 dB and ECC of less than 0.1 within the operating frequency band. The antenna provides the pattern diversity in H-plane, which can improve the performance of the antenna diversity.
