This paper presents a mono-cone antenna designed for Internet of Things (IoT) based smart cities and home automation with ultra-wideband (UWB) characteristics. The antenna exhibits an omnidirectional radiation pattern, enhancing its suitability for diverse applications. UWB technology with an omnidirectional pattern offers advantages for future IoT systems, offering high precision location tracking, secure communication, and high data transfer rates. The antenna design, comprising a circular disc ground plane and a truncated cone, demonstrates precise construction around the feed point, influencing high-frequency performance. The performance of the mono cone antenna is evaluated based on parameters such as S11, elevation, and azimuthal radiation patterns. Simulation results indicate that the antenna exhibits ultra-wideband characteristics, spanning from 2 GHz to 20 GHz with a gain varies from 4-7 dBi. Therefore, the proposed mono-cone antenna holds potential advantages for future IoT communication systems.
