Patent ID: 11264702

Abstract:
A wideband antenna transmits and/or receives electromagnetic radiation. The wideband antenna includes a feedline, a first dielectric layer, a via, a driven patch, a second dielectric layer, and a parasitic patch. The feedline couples a radiofrequency signal and an element of the wideband antenna. The first dielectric layer is between the feedline and the driven patch. The via couples the radiofrequency signal of the feedline through the first dielectric layer. The driven patch couples between the electromagnetic radiation and the radiofrequency signal of the via. The second dielectric layer has a low dielectric constant of less than 1.3. The parasitic patch is electrically isolated from the driven patch by the second dielectric layer between the driven patch and the parasitic patch. The parasitic patch electromagnetically couples with the driven patch and the electromagnetic radiation to produce a wideband frequency response of the wideband antenna.
