A Printed Wide‐Slot Antenna With Modified Tuning Stub and Parasitic Elements for Glucose Sensing Applications

Engineering Reports, Volume 8, Issue 7, July 2026.
A compact printed wide‐slot antenna with a diamond‐shaped tuning stub and parasitic elements achieves an ultrawide impedance bandwidth of 256% (2.4–16.2 GHz). Its capacitive nature enables frequency shifts with dielectric variations, making it highly suitable for accurate, non‐invasive glucose sensing applications.
