A Multiband Antenna For IoT Applications with Two Narrow-Single Wideband Including sub-6GHz 5G NR, WLAN and UWB-X Bands

In this work, a multiband antenna including two narrowband and single wideband is investigated. The proposed antenna is printed on Rogers RTDuroid 5880 substrate. The radiating patch is bifurcated as combination of patch and rectangular stub providing multiband. The proposed antenna comprises of compact size of 25×25 mm2 resulting in sub-6GHz 5G, WLAN and UWB-X bands. The proposed antenna is also analyzed by studying surface current density distribution and impedance. The far-field results offers good 2-D radiation patterns in all the three bands which makes it compatible for applications in hand-held devices and IoT.
