Antennas play a crucial role in IoT (Internet of Things) systems by facilitating wireless communication. Various types, such as patch, chip, wire, whip, PCB, and proprietary antennas, are tailored for specific applications. Choosing the right antenna ensures optimal performance, whether in smart homes or industrial IoT environments. This guide explores the different types of antennas used in IoT, highlighting their features and applications.
The Internet of Things (IoT) is a booming market. Day by day, IoT modules are becoming smaller, and the demand for incorporating more than one wireless technology is increasing. This has increased the demand for IoT antennas compliant with IoT modules. IoT applications are widely used for consumer and industrial markets for varied purposes, such as computations, sensing, as well as connecting things within the region.
In this page, we will cover IoT antennas of various types. These IoT topologies will help IoT module designers make the right choice of antenna.
Features of IoT Antennas
IoT antennas are uniquely designed to meet the specific requirements of IoT applications, offering a compact size, multi-band support, and low power consumption for seamless integration into small devices. They provide high efficiency and reliable connectivity in challenging environments, enabling communication across diverse frequencies like 4G LTE, Wi-Fi, LoRa, NB-IoT, and Zigbee.
IoT antennas are often optimized for long-range transmission, robust performance, and minimal interference, ensuring stable connectivity even in densely populated areas or remote locations. Additionally, they support IoT’s scalability by facilitating device-to-device and machine-to-machine communication across various industries.
IoT Antenna Types
The following table summarizes these IoT antennas.
| IoT Antenna Type | Description |
|---|---|
| Chip Antenna | Best option for small form factors and for lower frequencies, good for large productions due to low reproducibility issues. Chip antennas have low efficiencies and low bandwidth compared to other IoT antennas at the same frequencies. They need external matching despite having internal matching circuitry. They are sensitive to geometries related to ground plane. |
| Wire Antenna | Requires electromagnetic simulation for best-optimized design. The size of the antenna increases based on a decrease in the frequency. The prototype design of this antenna is very cost-effective, which helps in testing many versions during the design and development of the wire antenna. |
| Whip Antenna | Costliest among all the IoT antenna types, offering the highest performance and ideal when the IoT module faces cosite issues due to multiple transceivers. Needs a connector on the board of the module and a coaxial cable from PCB to antenna module. This antenna type requires emission testing to be performed. |
| PCB Antenna | This antenna is part of the pattern on the PCB. It is lower in cost and flexible in design. PCB antennas are available from lower to higher frequency range. Also, refer to patch antenna design used in mobile phones. |
| Proprietary Antenna | Designed by individual companies based on applications. |
Conclusion
Understanding the types of antennas available for IoT applications can greatly enhance system performance. Each antenna type offers unique benefits, making it suitable for specific use cases. By selecting the right antenna, IoT systems can achieve better connectivity and reliability.
