Significant advancement has been witnessed in the field of modern communication technology in last decade. Several wireless systems such as Wireless LAN, Wireless Fidelity (Wi-Fi) etc. are popular to connect devices to facilitate communication between them through internet technology. To access much faster communication, higher data rates are highly sought after with the upgradation of mobile communication generations (1G to 5G). Wideband/multiband antennas usually support multiple devices to get connected over a broad range of communication. As a benchmark of next generation communication technology, Internet of Things (IOT) is gaining a huge popularity in the field of wireless network. It ensures faster and secure communication among devices and cloud with high data rate. With this aim, we have proposed a new monopole antenna for IOT applications. The design consists of a new concentric ring based split ring patch and partial ground plane. It is implemented with characteristic mode analysis. The designed antenna operates in the ultra-wideband region with multiband characteristics at four bands of (1.5-1.9 GHz), (3.9- 4.2 GHz), (5.9-6.9 GHz) and (7.4-11.8 GHz) to cover for various IoT communication applications. The suggested design is inspected using analysis of characteristic mode, characteristic angle, eigen values, and modal significance. The distribution of surface current for the proposed circular shaped patch antenna is analyzed for mode of propagation by the theory of characteristic modes (CMA).
