Virtual Antenna™ technology enables one antenna component to cover all IoT frequency bands. This article describes the main features of Virtual Antenna™ technology and shows a simple design flow comprising only three simple steps.

Smart sensors, smart meters, smart tracking, smart factories, smart agriculture and all possible smart things you can imagine need to be connected. IoT enables connecting things with other things, in consequence a relevant player is needed which transmits and receives data to and from each thing: an IoT antenna.

Wireless engineers working on the development of the all the new bunch of IoT devices are looking for the best IoT antenna: the one covering all desired bands, with the smallest footprint and with the highest efficiency. On top of this, the antenna needs to be integrated in the design with other radiofrequency components such as modules, amplifiers, and filters, therefore, why not treat it as just another component?

Virtual Antenna™ technology enables one antenna component to cover all IoT frequency bands. The antenna called antenna booster is a very small chip antenna component able to be tuned to any frequency worldwide as needed. And because it is off the shelf, no customization on the antenna part will be needed so the IoT architecture becomes predictable from day one and is the ideal solution for mass production.

This paper presents the main features of Virtual Antenna™ technology and shows a simple design flow comprising only three simple steps on how wireless design engineers can embed Virtual Antenna™ in IoT devices.
