Patent No. US 9,407,001

COMPACtenna   …   COMPACT antenna


With a special design construct of spiraled metal sheeting, all resistance, inductance and capacitance (matching) is efficiently done by the physical metallic geometric form of the antenna itself, as opposed to internal or external (lossy) components of other designs.
This built-in resonating matching system is an effectual component of the electromagnetic field production, resulting in better performance than expected for such a small antenna.
And resulting diverse effective electromagnetic fields further enhance performance in our world of (dynamic) obstructions, mitigating signal drops, reducing flutter, and increasing reliable range.
