Embedded Antennas

Embedded antennas are antennas that can be integrated into the dielectric material of a printed circuit board. They are typically made of a thin metal layer and have a thickness of less than half a millimeter.
There are two main types of embedded antennas available:
1. Flex Antennas: These antennas are designed to be off board but can be embedded into the circuit board.
2. Patch antennas: They are single-layer structures that consist of an electrically conducting patch with one or more openings to allow electromagnetic fields to pass through the structure. However, microstrip and slot antennas are not relevant in this context.
