Abstract
Researchers at the University of Central Florida have
developed a reconfigurable modular antenna array that can be programmed to
operate over several different frequency bands while still using a common
antenna aperture. The antenna and transmitter design work as a mix-and-match
antenna array that is easily configurable and scalable to specific
applications. This simplicity allows for an easily manufactured design that is
capable of polarization diversity and single-side radiation over several bands.
Thus, the technology can cover a wide frequency range without having to
redesign the antenna system.
Technical Details
The invention comprises a reconfigurable antenna array and
methods for reconfiguring the array. By using a slot-ring design and RF
switches, the technology provides frequency reconfigurability and polarization
diversity without grating lobes. It can operate in S band (2-4 GHz), C band
(4-8 GHz), and X band (8-12 GHz) and is switchable in between the bands. With
varactors, the antenna array can cover the frequency range by continuously
tuning the center frequency with a relatively narrow instantaneous bandwidth.
Alternatively, a fractal shape enables the antenna array to realize a full-band
instantaneous bandwidth. Each frequency band has its own feeding lines.
Partnering Opportunity
The research team is looking for partners and potential
licensees to develop the technology further for commercialization.
