Wideband end-fed coaxial collinear antenna
This patent describes a new design for a coaxial collinear antenna — a type of antenna that stacks multiple radiating elements to boost signal strength in a wide, flat coverage pattern. The key innovation is an end-fed port located at the far end of the antenna, combined with wire meshes attached to the outer conductors of each cable segment, which together improve the antenna's ability to work across a wider range of radio frequencies than conventional designs. The segments are wired in a cross-coupled fashion (inner to outer and outer to inner) to create the collinear radiation effect. The result is a physically compact antenna that can cover more of the radio spectrum without needing to swap hardware.
What you could build
A wideband base-station or access-point antenna for wireless infrastructure operators — cellular carriers, private LTE/5G network builders, or public safety radio network vendors — who need a single antenna to cover multiple bands simultaneously without complex filtering or antenna arrays.
Who in Virginia should care
Virginia's large defense and federal communications sector — including DARPA contractors, DoD spectrum users at the Pentagon, and public safety network operators — would have practical interest in wideband antenna hardware.
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.
