WAMI Research Lab

Resources| Sponsors

Our wireless systems research spans terrestrial and satellite communication systems. This work includes measurement and statistical characterization of multipath in terrestrial wireless channels and developing signal and receiver structures for broadband wireless communication. In the area of satellite communications, we are studying propagation in millimeter-wave earth-space links as part of a multi-university effort; the goal is to explore approaches for fade event modeling and prediction, and geographical site diversity for fade reduction.

Active Devices

Excellent microwave active device characterization and CAD modeling capabilities are one of the strengths of USF's WAMI program. Recent focus has largely been placed on FET devices (MESFETs, HEMTs and pHEMTs) and PIN diodes, along with an increasing interest in silicon RFICs. Areas addressed range from small signal and noise modeling over bias and temperature to non-linear modeling in the frequency and time domain. USF has also bench-marked complete competence in monolithic microwave integrated circuit (MMIC) design and testing through its "University Foundry Training" project.

Passive Circuits

Our passive circuit research targets advances in design, fabrication and characterization of lumped and distributed components, from surface mount parts to 100 GHz planar distribution networks. We are also applying MEMS (micro electromechanical systems) processing techniques to the development of new methods for manufacturing extremely low loss, tunable micro- and mm-wave circuits.

Antennas

Antenna research is focused on planar architectures, such as slot and patch antennas, for such applications as on-board automotive sensors (occupant sensing and anti-lock brake systems) and wireless personal communications. As part of their studies, students acquire a range of research and development skills through the use of our research facilities, shown below.
