Antenna device and method of generating polarized signals

An optical sensing circuit including a capacitor, a light sensing unit, a compensation unit, and a switching element is provided. The light sensing unit, the compensation unit, and the switching element are electrically connected to the capacitor. The light sensing unit senses the light of a first color. The compensation unit senses the light of a second color complementary to the first color. When a light illuminates the light sensing unit and the compensation unit, a first light component of the light corresponding to the first color causes the light sensing unit to generate a first current, and a second light component of the light corresponding to the second color causes the compensation unit to generate a second current, which reduces the amount of the charging or the discharging current when the first current charges or discharges the capacitor whose voltage is read as information for determining light color.
