As antenna gain increases, beamwidth tends to:

Higher antenna gain concentrates the radiated energy into a smaller angular region, so the beam becomes narrower. Gain and directivity describe how focused the radiation is: increasing gain means more energy is directed in a specific direction, which tightens the main lobe of the pattern. This is typically achieved by a larger aperture or better focusing, which reduces the angular spread of the radiation. The practical effect is a stronger signal in the intended direction but a narrower coverage area unless you rotate or steer the antenna to cover more angles.
