Abstract
The article presents an innovative transparent, flexible antenna design tailored specifically for ultra-wideband multiple-input multiple-output (MIMO) systems. Using polyethylene terephthalate substrates as the base material, we enhance the antenna’s radiation performance, transparency, and flexibility. Broadband impedance matching is achieved through a hollow ground plane fed by a fish-tail radiator and coplanar waveguide. Additionally, significant MIMO antenna isolation in ultra-wideband scenarios is achieved through the vertical arrangement of units and neutral lines. The MIMO antennas we manufactured exhibit minimum transparencies of 71.1% and 85.9% with and without reflectors, respectively. Measurement results demonstrate that the antenna operates within the 3–20 GHz frequency range, with over 24 dB of isolation, 2 ± 2 dBi of peak gain, and 45% ± 5% of radiation efficiency, suitable for applications in wearable devices, vehicle intelligence, and other fields.
期刊介绍：
Flexible and Printed Electronics is a multidisciplinary journal publishing cutting edge research articles on electronics that can be either flexible, plastic, stretchable, conformable or printed. Research related to electronic materials, manufacturing techniques, components or systems which meets any one (or more) of the above criteria is suitable for publication in the journal. Subjects included in the journal range from flexible materials and printing techniques, design or modelling of electrical systems and components, advanced fabrication methods and bioelectronics, to the properties of devices and end user applications.
