Summary
The Internet of Things (IoT) is the future technology, whose glimpses are already visible in various fields today. IoT promises a connection of about 50 billion devices in the near future to enhance data sharing and analysis between many otherwise independent modules. Smart sensors, smart antennas, and intelligent processors form the backbone of IoT technology. IoT is about remote detection and control of devices which is dependent on the efficient communication system provided. This paper studies the IoT technology, along with its supportive systems, giving an emphasis to the communication module, enabled using microstrip patch antennas. The study takes a walk through the different improvement techniques implemented in patch antennas as DGS, MIMO, and arrays and further pins down the research gaps and objectives that can be taken up in this field with respect to the effective implementation of IoT services. Recent advances in the antenna systems employed in IoT environment are discussed, and the antennas employed in IoT devices and applications are reviewed in detail. Recently evolving technologies like LoRa and NB‐IoT and the ESP8266 module which is widely used in IoT applications are addressed. A good insight is given into the challenges faced in this field along with some recent case studies.
