Abstract: An antenna device includes a first antenna unit, a second antenna unit and a third antenna unit. An angle between the second antenna unit and the first antenna unit is substantially equal to 90 degrees. An angle between the third antenna unit and the first antenna unit is substantially equal to 90 degrees. The first antenna unit and the second antenna unit are configured to generate a signal having a first polarization when the third antenna unit is turned off. The third antenna unit and the second antenna unit are configured to generate a signal having a second polarization different from the first polarization when the third antenna unit is turned off. A method of generating polarized signals is also disclosed herein.

Abstract: An antenna device includes first to third antenna units and a feed-in line. An angle between the second antenna unit and the first antenna unit is substantially equal to 90 degrees. An angle between the third antenna unit and the first antenna unit is substantially equal to 90 degrees. The feed-in line crosses over each of the first to third antenna units in a view, and is configured to turn on and turn off each of the first to third antenna units. The first antenna unit and the second antenna unit are configured to generate a first polarized signal, the third antenna unit and the second antenna unit are configured to generate a second polarized signal, and the first polarized signal and the second polarized signal have different polarizations.

Abstract: An optical sensing circuit includes a first, a second, and a third optical sensing element and a sampling circuit. The first sensing element provides a first current from a first node to a second node according to an ambient light and a sensing signal. The second optical sensing element drains a second current from the second node to the first node according to the ambient light and the sensing signal. The third optical sensing element is coupled between the first node and the second node. The third optical sensing element receives a first color light, and transmits the first current to the second node or transmits the second current to the first node according to the first color light. The sampling circuit is turned on according to the sampling signal to output a detection signal based on the voltage level of the second node.
