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 several types of embedded antennas available:
- Flex Antennas: These antennas are designed to be off-board, adhesively mounted to a device enclosure, and connected to the PCB with a micro-coax cable and connector.
- PCB Antennas: FR4 antennas are antennas built on a substrate made from glass fiber-reinforced epoxy laminate and used in various wireless devices due to several advantages: Low cost, Compact size and Easy to integrate.
- Patch antennas: Ceramic patch antennas are a specific type of patch antenna that uses a ceramic substrate instead of the more common FR4. This difference in material leads to several advantages including higher permittivity, better mechanical strength and higher temperature stability.
