Wideband frequency shifting via single high-Q antenna
This technology enables a high-Q antenna — the kind that normally operates efficiently only within a very narrow frequency band — to rapidly switch between multiple frequencies while preserving the energy already stored in the antenna. It does this by timing the frequency switch to coincide with the zero-crossing point of the signal, preventing energy loss that would typically degrade transmission quality. The result is that a single compact, efficient antenna can behave like a wideband antenna, transmitting across a broad spectrum without needing bulky hardware for each frequency. This is particularly relevant for software-defined radio and next-generation wireless systems where spectrum agility is critical.
What you could build
A software-defined or cognitive radio module that uses a single compact high-Q antenna to cover wide frequency ranges, sold to military communications integrators, IoT device manufacturers, or handset chipset vendors needing spectrum-agile hardware in a small form factor.
Who in Virginia should care
Northern Virginia and Hampton Roads defense contractors (Leidos, Northrop Grumman, L3Harris) and DoD program offices focused on software-defined radio and spectrum-agile communications would be natural targets.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
