Direct-excitation transmitter for small-antenna IoT devices
This technology enables small antennas to transmit data wirelessly without needing a variable power supply, which is typically a costly and complex component. Instead, it uses a switched capacitor — essentially a tiny circuit element that rapidly alternates between charging from a fixed voltage source and then delivering that charge directly to the antenna. By doing this, the circuit simultaneously tunes the antenna to its optimal operating frequency and drives it to emit a signal. The result is a simpler, more compact transmitter architecture that can achieve high data rates from a physically small antenna using basic, low-cost electronics.
What you could build
A compact, low-cost wireless transmitter module for IoT sensors, wearables, or embedded devices where size and power simplicity are critical; target buyers would be IoT hardware manufacturers and defense contractors building miniaturized communication systems.
Who in Virginia should care
Defense electronics and communications firms in Northern Virginia and the Hampton Roads corridor — particularly contractors building compact, low-power radio systems for embedded or unmanned platforms — would have direct interest.
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.
