Erratum to “Miniaturized Printed Inverted-F Antenna for Internet of Things: A Design on PCB with a Meandering Line and Shorting Strip”

---

In the article titled “Miniaturized Printed Inverted-F Antenna for Internet of Things: A Design on PCB with a Meandering Line and Shorting Strip” [1], there were errors in Figures 3, 4, and 6. In Figure 3, the “” and “” were missing, in Figure 4, the “” was missing, and in Figure 6, the numbers −30, −25, −20, −15, and −10 were mistakenly written as −35. These errors occurred during the production process. The correct figures are as follows.
