RF/Microwave and Antenna Design


Summary

RF / Microwaves, and Antennas group at the University of North Texas will conduct research in the areas of RF / microwave / millimeter-wave circuit and antenna design. Applications include wireless communication system, satellite / space system, and military system. Designed circuit components will be implemented either on the board-level or on the chip-level. And we have good facilities for simulation, fabrication, and measurement of these circuits.

Facilities

The Department of Electrical Engineering at the University of North Texas offers good facilities for simulation, prototyping, and measuring RF / microwave circuits and antennas. As for the simulations, we have CAD tools such as Cadence and ADS. As for the fabrication, we have state-of-the-art PCB fabrication facilities and a new clean-room will open in 2010. For the measurement, we have excellent equipments such as vector network analyzer, spectrum analyzer, signal generator, digital oscilloscope, signal analyzer, and antenna pattern measurement facility.

Recent and ongoing work:

  • Designs of compact, multi-functional, and multi-band microwave circuits for communication systems.
  • Designs of novel ultra-wideband antennas.
  • Antennas for wireless sensor network applications.
