I am designing a PCB layout for NXP JN516x Wireless Microcontroller (http://www.nxp.com/docs/en/data-sheet/JN516X.pdf). Part of the design is the antenna, where I have to choose a 50ohm antenna. I decided to go with a chip antenna (https://www.digikey.com/product-detail/en/ethertronics-inc/1001312/939-1040-1-ND/4754415), since it has a small footprint. According to the NXP JN516X datasheet, There is a matching network for the antenna, as shown in the figure below:

[![enter image description here][1]][1] But I can see from the datasheet of the antenna itself, there is a recommended PCB Layout, where it is clear in the below figure that there is only two matching components, and the datasheet didn't even mention anything about the values or whether they are inductors or capacitors.

I don't have much experience with antenna design. Which matching network should I use, the one in NXP datasheet or the one in the antenna datasheet?

Thanks in advance.
