Ultra-Wideband (UWB) Antenna with Integrated Band-Notch Characteristics for Interference Suppression in IoT Devices

Abstract

A tiny Band-Notched (BN) Ultra-Wide Band (UWB) antenna with incorporated Internet of Things (IoT) has been designed for personal wireless connections and IoT applications. The antenna functions within the UWB frequency (fz) range (3.2-11.7 GHz) and IoT (2.5-2.595 GHz), exhibiting BN properties at the Wireless Local Area Networks (WLAN) fz bands (5-6.5 GHz). A novel method for incorporating IoT into a UWB BN antenna has been devised and evaluated. The UWB fz band is achieved using a standard cylindrical radiated patch and altered partial grounding planes. The IoT bands are incorporated through a tiny resonator supplemented by capacitors. To accomplish this objective, a typical slot-resonance is integrated into the radiation to reduce the impact of the WLAN fz band inside the UWB. The UWB Antenna (UWBA) has been built and manufactured, and its reaction for each scenario is presented. The UWBA demonstrates an effective irradiation structure with consistent gain within the passband. The current antenna is contrasted with cutting-edge constructions presented in the research. The antenna’s compact dimensions (32 × 33 mm) render it an exemplary contender for UWB and IoT applications.
