Internet of Things (IoT) is becoming a driving paradigm for the Information and Communication Technology (ICT) evolution. This paradigm is not a revolution, yet is a way to look at, use and evolve existing technologies and apply them to new solutions. Among these technologies, Wireless Power Transmission (WPT) and related ones can be certainly considered enabling for IoT. WPT in fact, on the one hand...
The design of complex RF devices such as oscillators, amplifiers and mixers requires accurate CAD simulations. Usually these devices are designed by using the “Harmonic Balance” frequency domain technique that calculates the magnitude and phase of voltages (or currents) in a non-linear circuit. The passive part of the sub-system (matching circuits, filters, feeding networks) is simulated exploiting...
In this work, a new technique to fabricate microwave circuits in paper substrates is adopted. This technique relies on a copper adhesive tape that is shaped by a photo-lithographic process and then transferred to the hosting substrate by means of a sacrificial layer. Microstrip lines in paper substrates have been electromagnetically characterized accounting also for the adhesive layers. Then a simple...
