Abstract
A patch antenna is presented herein. The patch antenna can include a substrate layer, a dielectric layer and a conductive layer. The substrate layer can include a hollow thermoplastic structure. The dielectric layer can be attached to a surface of the substrate layer. Furthermore, the dielectric layer can include a thermoplastic structure filled with a fluid. The conductive layer can be associated with another surface of the substrate layer.

A patch antenna, comprising:
- a substrate layer that comprises a first thermoplastic structure that comprises a first cavity filled with air, wherein the first cavity contains a feeding probe for the patch antenna;
- a dielectric layer that is attached to a first surface of the substrate layer and comprises a second thermoplastic structure that comprises a second cavity filled with a nonmetal fluid;
- and
- a conductive layer that is attached to a second surface of the substrate layer and the feeding probe contained within the first cavity filled with the air.
