I am currently designing a custom board for my nRF54L15 project and I would like to know if the "Antenna" pin on the nRF54L15 can have a DC path to ground/ground layer of my circuit board? I intend using an "Inverted F Antenna" which has a DC path to ground through its structure. I intend using the filter as per the NRF54L15 reference design and directly connecting its output to the feed port on my Inverted F Antenna. Or, do I need a coupling capacitor between the filter output and the feed port of my Inverted F Antenna?
The Inverted F Antenna I intend using is documented here :- http://www.ti.com/lit/an/swru120d/swru120d.pdf?&ts=1589387711922 See page 2 where 50 ohm feed point and ground plane connections are shown.
Any help here will be greatly appreciated.

SteveH
