the antenna doesn't actually start until the ground and RF conductors diverge. if you implement that trace as a transmission line and match the impedance of that trace to the nominal system impedance, the trace will simply transmit all power into the antenna and not radiate anything. Pic related, transmission line calculator included with KiCAD, having calculated the correct width of the trace to create a 75 ohm microstrip transmission line on a typical substrate with 1 oz. copper (but you'll probably want to use a 50 ohm system impedance by default). there are many other such calculators. JLCPCB has one with presets for their board substrates
you should take a little detour into transmission line theory next
