  In this correspondence, we study deploying movable antenna (MA) array in a
wideband multiple-input-single-output (MISO) communication system, where
near-field (NF) channel model is considered. To alleviate beam squint effect,
we propose to maximize the minimum analog beamforming gain across the entire
wideband spectrum by appropriately adjusting MAs' positions, which is a highly
challenging task. By introducing a slack variable and adopting the
cutting-the-edge smoothed-gradient-descent-ascent (SGDA) method, we develop
algorithms to resolve the aforementioned challenge. Numerical results verify
the effectiveness of our proposed algorithms and demonstrate the benefit of
utilizing MA array to mitigate beam squint effect in NF wideband system.
