As the world is getting used to 5G technology, 6G is already on the horizon. With the ultimate goal of very low latency communication and Tbps data rates, 6G supports new wireless technologies such as virtual and augmented reality and autonomous driving. In this new generation of wireless communication, high frequencies up to 100 GHz are used...

The interest for phased array antennas has increased over the past years along with the need for wide bandwidth arrays. Connected arrays are becoming more prevalent as a well suited solution to achieve the desired bandwidth. In order to increase the bandwidth and the scan angle of this type of array, horizontal artificial dielectric...

In transit-time ultrasonic flow measurement systems, the system's ability to operate reciprocally in the absence of flow is a highly desirable property. If the reciprocity is lacking in the system, any time delay that appears between the upstream and downstream signals at zero-flow conditions will result in false flow measurement. This...

This report discusses one part of a project consisting of three parts. The goal of the project is to design a battery less sensor powered by RF energy fields present in an office environment. The sensor is able to measure the temperature and is able to communicate wirelessly using a low power communication protocol.In this report the energy...

In this paper we present the design and simulation results of an RF energy harvesting circuit that operates across a wide range of available input power, from -27 dBm to 6 dBm. The system comprises an adaptive impedance matching network, a single-stage cross-connected differential rectifier, a start-up charge pump, an adaptive buck-boost...

Some systems like RF energy harvesters have power transfer efficiency as one of the most important specifications. Therefore, the efficiency of the matching network, which affects the entire system’s efficiency, plays an important role. When the impedance transformation factor between the antenna and its load is high, the matching network...

With the evolution of wireless communication, varactors can play an important role in enabling adaptive transceivers as well as phase-diversity systems. This thesis presents various varactor diode-based circuit topologies that facilitate RF adaptivity. The proposed varactor configurations can act as variable capacitors with high tuning range,...
