Antenna selection should be made at the beginning of development for any wireless IoT device because its final cost and performance will define the success of your project.<\/p>\n

Understanding what makes an antenna<\/h2>\n

Everything inside a distance of pi x 2 x lambda to antenna component becomes part of the system and affects its performance. This area is called the \u201cnear field \u201cof the antenna, this will include the PCB, larger components such as the battery or display, the FR4 board and the housing.<\/p>\n

Below we will illustrate a few known and also a few unknown arrangements for antennas in a tracking device transmitting over NB-IoT, LTE-M, GNSS and Bluetooth. The ten examples shown are only symbolic, there are many more possibilities and these could fill an entire “IoT Antenna Cookbook”.<\/p>\n

Possible antenna arrangements<\/h2>\n

10 illustrations of antenna layout on a PCB<\/p><\/div>\n

Figure 1 and 2 show chip antennas for NB-IoT\/LTE-M, Bluetooth and GNSS. In figure 3, the chip antenna for GNSS \u201cc\u201d has been exchanged for a patch antenna. In figure 4, the chip antenna for NB-IoT\/LTE-M (g) has been exchanged for a flex PCB antenna. This is not unusual and saves installation space on the PCB. The downside is the extra cost of the antenna, the coaxial socket on the PCB and the cost of manual labour to mount the antenna in the enclosure.<\/p>\n

PCB antennas integrated into the main PCB with chip antennas
In Figure 5, the PCB antennas for NB-IoT\/LTE-M have been integrated into the main PCB. This has several advantages: the cost of procurement is 0 Euros, the delivery time is 0 days and there is no end of life. In addition, the antenna can be optimally adapted to the environment by adjusting the antenna structure. Chip antennas were chosen for Bluetooth and GNSS.<\/p>\n

Introducing the akorIoT SensPRO<\/h2>\n

akorIoT SensPRO multi-antenna PCB<\/p><\/div>\n

Here is a practical example of a multi-antenna test PCB, the akorIoT SensPRO, The SensPRO has a PCB antenna for NB-IoT\/LTE-M and a chip antenna for GNSS, in addition there is a PCB antenna for Bluetooth included on a separate Bluetooth module<\/p>\n
