Abstract: The present application discloses a sensing screen, a control circuit and control method thereof, and a sensing screen apparatus. The sensing screen includes a display screen, a first transparent medium layer, a transparent connection layer, and an antenna layer. The antenna layer includes multiple antenna units, and the antenna units include at least one first antenna unit and multiple second antenna units. The first antenna unit is configured to transmit a sensing signal, the second antenna units are configured to receive reflected signals of the sensing signal, and the reflected signals are generated by a touch object by reflecting the sensing signal. According to the present application, the antenna layer is arranged right above the display screen, so that a touch area of the sensing screen is fully utilized while screen display is not affected, so as to substantially increase an antenna size and increase an antenna gain.

Abstract: The present disclosure provides an array antenna. The array antenna includes a cavity power divider that receives an input signal and performs power division to output a first power-divided signal. The array antenna also includes a final-stage power dividing, coupling, and radiating unit that includes a dielectric substrate and a first and a second metal surface layer. A coupling slot array is formed on the second metal surface layer to receive the first power-divided signal. A radiating slot array corresponding to the coupling slot array is formed on the first metal surface layer; Several plated through-hole units are provided on the dielectric substrate, where the plated through-hole units go through the first and second metal surface layers vertically, and a range corresponding to each plated through-hole unit encloses a coupling slot and a radiating slot corresponding to the coupling slot.
