Multifunctional Antenna Design for Internet of Things Applications

Internet of Things (IoT) can play a significant role in the process of communication between contemporary devices across the network. IoT allows many smart, internet-enabled devices to connect with each other in real-time. Efficient hardware, along with sophisticated and robust communication protocols, plays a crucial role in the functioning of communication networks. Antennas are used for transmitting and receiving signals in communication devices and are thus an essential part of all IoT devices. IoT antennas should be energy-efficient, compact, and able to work in multi-antenna configuration. This paper presents a miniaturized multifunctional multiple-input–multiple-output (MIMO) antenna that can be conveniently used in IoT devices. The proposed antenna covers different wireless technologies and communication standards used commonly by IoT systems. The obtained results demonstrate that the MIMO antenna exhibits broad bandwidth and low correlation among the resonating elements.
