Time-variant antenna enabling wideband transmission in small
This technology enables a small antenna to rapidly switch its operating frequency between two values by alternately connecting different capacitors to the antenna—and doing so precisely at the moment when voltage is zero, which avoids energy loss and interference. The result is a compact antenna that can transmit wideband signals despite its small physical size, a longstanding challenge in antenna design. The switching is controlled by a modulation signal, allowing the antenna to mimic the behavior of a much larger antenna across a wider frequency range. This is useful anywhere a small form factor is required but broad frequency coverage is needed.
What you could build
A miniaturized wideband radio module for IoT devices, small satellites (CubeSats), or tactical military radios where size constraints prevent use of conventional broadband antennas; defense electronics integrators and IoT chipset makers would be the primary buyers.
Who in Virginia should care
Defense electronics contractors and communications hardware companies with presence in the Northern Virginia/DC corridor or Hampton Roads defense cluster would find direct relevance here.
Readiness: Lab validated
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.
