Abstract
Wearable antennas are increasingly being developed to support devices, sensors, and communication tools that users can wear flexibly and comfortably. With the advancement of mobile communication technologies such as 5G (fifth-generation), which supports high data rates, wearable antennas can be integrated with Multiple Input Multiple Output (MIMO) technology, capable of increasing channel capacity and data transmission speeds. One of the main frequency bands allocated for 5G technology is 3.5 GHz, which was therefore selected as the operating frequency for this study. This study designed a two-port MIMO wearable microstrip antenna based on a denim substrate operating at 3.5 GHz. To improve its performance, the Defected Ground Structure (DGS) method and parasitic elements were applied. The antenna was designed and simulated using Ansys HFSS, then fabricated and measured for validation. The simulation results for the final antenna design with dimensions of 48 mm x 32 mm show a return loss of -36.173 dB, a VSWR of 1.032, mutual coupling of -30.414 dB, gain of 3.844 dBi, bandwidth of 466 MHz, radiation efficiency of 89.217%, ECC approaching zero, diversity gain of 10 dB, and an omnidirectional radiation pattern. The antenna continues to perform well under bending conditions, and the measurement results are close to the simulation values. The results of the designed antenna meet the target specifications and performance requirements for a wearable MIMO antenna.
