Flexible antennas with tape.
If your antennas cannot be located on the PCB, and cannot be mounted externally, a flex antenna can be a very good the solution.
Flex antennas are mounted on the enclosure using adhesive tape.
The antennas come with a cable including a UFL / IPEX connector, to be mounted on PCB or directly on a wireless modem-cards solution.
Naturally the Radome / enclosure material need to be RF transparent, like most plastic materials.
Some flex antennas can be bended & corner mounted, or even be mounted on metal and have directional radiation pattern.
We offer flexible FPC antennas for many applications.
