Beschreibung
Zusammenfassung:	A touch detection device comprises: a cradle capable of being mounted on one end of a display; an antenna including a transmitter for transmitting a signal and a receiver for receiving the signal reflected to an object; a dielectric lens limiting a first directional radiation angle of the transmitted signal; and a control unit calculating the coordinates of an object based on the signal received from the receiver. Therefore, the touch detection device can detect the coordinates of an object based on the signal reflected from the object by limiting the radiation angle of the transmitted signal. 디스플레이 일단에 거치할 수 있도록 하는 거치대; 신호를 송신하는 송신부 및 상기 신호가 객체에 반사되는 신호를 수신하는 수신부를 포함하는 안테나; 상기 송신된 신호의 제1 방향 방사각을 제한하는 유전체 렌즈; 및 상기 수신부에서 수신된 신호를 기반으로 상기 객체의 좌표를 계산하는 제어부를 포함하는 터치 감지 장치는 송신신호의 방사각을 제한하여 객체에서 반사되는 신호를 기반으로 객체의 좌표를 감지할 수 있다.
