Disclosed is a device and method for inputting characters or drawings on a mobile terminal using a virtual screen. To input characters or drawings through a virtual screen, the mobile terminal includes an electronic pen, a virtual screen generator, a position detector for detecting the electronic pen position, and a character recognition algorithm for recognizing a trail as a character. When a signal is input from the electronic pen, the mobile terminal detects the originating position of the signal and its trail. The mobile terminal recognizes the detected trail as a character and generates a virtual screen with the recognized character.

A portable terminal includes an antenna device having a circuit board on a surface of which a conductive layer is formed, a slit that removes a portion of the conductive layer and extends in a direction, an auxiliary board positioned on the slit to face a surface of the circuit board, and a radiation pattern formed on the auxiliary board, in which the radiation pattern is disposed to partially enclose the slit. Even when the radiation pattern is disposed on the conductive layer, induced current generated around the slit can be controlled in the same direction as signal power, thereby preventing radiation performance from being degraded by an inverse current phenomenon in spite of disposition of the radiation pattern on the conductive layer.

A Multiple-Input Multiple-Output (MIMO) antenna system with multiple antennas is provided. The MIMO antenna system includes a number of conductive elements, and a number of band stop devices. The conductive elements are spaced apart from each other and operate in corresponding resonant frequency bands respectively when they receive electric power. When the conductive elements are operated, the band stop devices block interference between the conductive elements in the resonant frequency bands, and isolate the conductive elements from each other. The band stop devices are located between adjacently separate conductive elements and connect the conductive elements to each other. The MIMO antenna system can stop interference between the conductive elements via the band stop devices, thereby increasing the operational efficiency of the conductive elements.
