I have the following concern in a design that I am carrying out. I am working on the development of an electronic prototype that uses as a CPU the module: PICO-IMX6-SD. This module has wifi and Bluetooth connectivity and for this uses the BCM4339 chip of the Broadcom company. But in order to provide this functionality you must connect an external antenna through a ufl connector. My device consists of a base PCB which contains a 70-pin hirose connector that allows connection to the module PICO-IMX6-SD, I do not want to add an external antenna to the device for some reasons, but I want to include a chip antenna on my PCB. My question is this: if I add the antenna and I put a ufl connector, then when connecting both ufl connectors through a female-female cable would have Bluetooth connectivity? Or there is the possibility of potential failures. In general lines I have not found a design that uses the BCM4339 together with an on board antenna. A clearer way to explain this is the following: the Intel company launched the Intel Edison module, it has an on board antenna chip for the Bluetooth connection. This module was discontinued, in the prototype I use this module, but I replaced it with the PICO-IMX6-SD. Now I want to add a chip antenna just like the one the Edison has. What recommendations do you suggest? I'm thinking of using some Murata chip antenna.
