A dielectric layer for use in an antenna assembly, the dielectric layer comprising:
- a planar body formed using a dielectric material;
- and
- a plurality of openings defined in the planar body and surrounding a plurality of portions of the dielectric material, each of the plurality of portions of the dielectric material being configured to be aligned with an antenna element of a plurality of antenna elements of the antenna assembly.
An antenna assembly comprising:
- a printed circuit board (PCB) assembly;
- at least one antenna layer at least partially forming a plurality of antenna elements;
- and
- a dielectric layer located between the PCB assembly and the at least one antenna layer and having a dielectric constant of between 2.5 and 3.5 and a coefficient of thermal expansion (CTE) of between 15 parts per million per degree Celsius (ppm/° C.) and 25 ppm/° C.
A method of assembling an antenna assembly, the method comprising:
- obtaining at least one antenna layer at least partially forming a plurality of antenna elements;
- obtaining a printed circuit board (PCB) assembly;
- obtaining a dielectric layer having a planar body formed using a dielectric material, and a plurality of openings defined by the planar body and surrounding a plurality of portions of the dielectric material;
- and
- stacking the dielectric layer between the at least one antenna layer and the PCB assembly such that each of the plurality of portions of the dielectric material is aligned with an antenna element of the plurality of antenna elements.
