IoT projects rely on wireless connections, and the quality of wireless connection signals depends on the chip itself and the antenna.
IoT projects rely on wireless connections, and the quality of wireless connection signals depends on the chip itself and the antenna.
Wi Fi is the preferred choice for portable devices or IP cameras, while industrial applications such as remote monitoring, smart meters, smart buildings, smart cities, manufacturing automation, smart agriculture, and tracking are more likely to use LP-WAN networks such as NB IoT, LoRa, SigFox, ISM 791-960MHz, or cellular networks. Each type of network has various embedded antennas.
The selected antenna should seamlessly integrate into the PCB layout. In addition, it must operate within the required range, operate without interference, and use reasonable power levels. When entering the testing phase, the performance of all antennas will be validated, but choosing antennas wisely and designs that meet their requirements will give the design a good start.
At first glance, a small-sized antenna seems to be the best, but there are more factors to consider. The topology of an antenna determines its efficiency, bandwidth, radiation direction, and gain, so the smallest antenna may not be the optimal choice.
