Abstract
Methods and systems for laser etching substrates to fine tune antennas for wireless communication are provided. A method includes laser etching an antenna element design into a substrate material. The antenna element design is for receiving conductive material to form an antenna structure. The method also includes laser etching a first area of the substrate material to change an intrinsic property of the substrate material in order to control an electrical characteristic of the antenna structure.

An antenna structure comprising:
- a substrate material having laser etched therein an antenna element design, wherein the substrate material is characterized by an intrinsic dielectric constant;
- and
- conductive material formed within the antenna element design;
- and
- wherein the substrate material has further laser etched therein a first area that has a dielectric constant different than the intrinsic dielectric constant of the substrate material, and wherein the first area tunes a resonant frequency of the antenna structure to within a tolerance range of a desired resonant frequency.
