Elliptical slotted circular dual-port UWB MIMO flexible antenna for wearable applications
Abstract
This work describes a dual-port body-compatible ultra-wideband MIMO antenna engineered for wearable devices. The antenna has an elliptical-slotted modified circular patch with a defective ground structure, ensuring isolation above 20 dB covering the complete operating bandwidth. At 6.4 GHz, the radiator exhibits a peak gain of 2.4 dBi. The antenna maintains stable impedance matching under a variety of bending circumstances, demonstrating its mechanical flexibility and dependability for body-worn applications. MIMO diversity measurements show good performance, with an ECC < 0.001, DG z 10 dB, TARC < -10 dB, MEG < -3 dB, and CCL < 0.40 bps/Hz.
