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.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.
