Dual-band, dual-polarization antenna for phased-array systems
This antenna design combines two frequency bands and two perpendicular polarizations into a single compact element built on a layered circuit board. A square ring cut into a conductor layer handles the higher frequency, while a shorted square ring handles the lower frequency; both structures are fed independently through built-in transmission lines. The result is a single antenna that simultaneously transmits or receives signals at two different frequencies, each with two orthogonal polarizations — a combination that normally requires multiple separate antennas. The design supports circular or linear polarization depending on how the geometry is configured.
What you could build
A compact antenna element for phased-array systems used in satellite ground terminals, MIMO base stations, or airborne radar platforms; primary buyers would be defense electronics primes, satellite communications hardware manufacturers, and telecom equipment OEMs.
Who in Virginia should care
Northern Virginia and the Hampton Roads corridor host major defense primes, satellite operators, and DoD program offices that routinely procure advanced antenna subsystems.
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.
