The antenna is a crucial element when designing IoT devices.
Antennas are to wireless devices, what wheels are to cars. With excellent wheels, you can go safe, further, and optimize power consumption.
In this MDPI paper we can see comparison of two antenna technologies: Flexible Printed Circuit (FPC) antennas versus VirtualAntenna(R).
