Research Statement:
Prof. Bernhard's research addresses applications-oriented electromagnetic problems with an emphasis on theoretical analysis and experimental investigation. Her research group focuses on two areas: Electromagnetics for Wireless Communication and Reconfigurable Active and Passive Antennas.
Electromagnetics for Wireless Communication: This work centers on cutting-edge technology development and design techniques that will enable high data-rate wireless communication and wireless parallel computation. Prof. Bernhard's research group investigates the effects of packaging on antenna performance and uses these results to develop design-oriented models for internal antennas, embedded antennas, and diversity schemes. The research also creates synthesis approaches for internal portable antenna systems that produce desired performance while reducing user exposure and battery usage.
Reconfigurable Active and Passive Antennas: Prof. Bernhard's research implements reconfigurability in antenna structures to provide flexibility in operating frequency, bandwidth, and radiation pattern performance. Reconfigurability is accomplished using MEMS (microelectromechanical system) or traditional microwave switches, ferroelectric materials, or mechanical actuation of antenna components. The new multi-function antennas developed in this research will reduce dramatically the number and size of large array-based antenna systems, improve system efficiency, and decrease system cost and weight.
The research group is supported by a specialized fabrication facility, a new anechoic chamber (the Illinois Wireless Wind Tunnel), Agilent vector network analyzers, and opportunities for collaborations with the UIUC Center for Computational Electromagnetics.

Undergraduate Research Opportunities:
Students with an interest in applied electromagnetics, including antennas and high frequency circuits, are encouraged to contact me via e-mail. The background required for an undergraduate research position in my lab includes good performance in ECE 329 and ECE 450, with other advanced EM courses always a plus. For first- and second-year students who haven't taken these courses yet, opportunities may exist from semester to semester to help with the research projects of advanced undergraduates or graduate students, but at a more basic level.
