Wideband Planar Coupled-Feed Antenna for Internet of Things Applications

In this paper, a compact wideband antenna is proposed for Internet of Things (IoT) applications. This proposed antenna consists of one top metal strip and one bottom metal patch on the printed circuit board (PCB). By adjusting the length of the strip, the frequency range of this antenna is easily adjusted and tuned. This proposed antenna has the advantages of simple and planar structure as well as wide frequency range. This proposed design shows that the overall result is the same as result of conventional individual antenna. Both simulated and experimental results were performed, which show the overall performance is suited for IoT applications.
