Since the popularisation of mobile devices, the demand for cellular network access has been exponential across a wide range of IoT applications. The fast speeds, high bandwidths and large coverage of cellular networks make them a perfect choice for long range and remote devices as well as precise, real-time applications. Cellular antennas are designed to take advantage of the potential of cellular connections through the 3G, 4G/LTE and 5G bands. The applications of the devices that use these antennas can vary from smartphones and wearables to remote surgery and self-driving vehicles. Challenges of sacrificing battery life for speed and PCB space in these industries are prevalent. That said, the small ground plane size of cellular antennas has little impact on their performance and makes them the perfect solution to these hurdles.
