Tuning Chip Antenna

I am designing a BLE board with nrf52832. This is the first time I am designing a board having a RF part. After considering MIFA and Chip antenna, I have decided to use Chip antenna as I think it will be easy for me to incorporate in my design.

However, I read and do understand that MIFA antenna requires tuning by adjusting it's length as near-by material and/or pcb variation may change electrical length of antenna trace. And I think chip antenna should have provision to tuning but I am not aware of it. Do I need to tune a chip antenna? If yes, then how?

I am designing the board for this chip antenna. The datasheet states the antenna has 50 ohm impedance. Can I skip matching network suggested in the datasheet if my antenna feed line (coplanar transmission line with ground plane in the bottom) is also of 50 ohm?

• @LiorBilia: If there is no difference between a PCB antenna and chip Antenna, then it is a duplicate question! – abhiarora Oct 24 '17 at 17:47
• The process is the same, the tools are the same, for all purposes, it is the same. – Lior Bilia Oct 24 '17 at 23:06
