A mobile terminal is provided to remove a harmonic component generated in the process of amplifying a Tx signal, without any additional filter or filter replacement, by forming a certain pattern at a grounding surface located below a main board's signal line through which Tx signals are transferred. A mobile terminal comprises a communication part and a main board. The communication part comprises an amplification part which amplifies Tx signals. The main board, on which the electronic components of the communication part are mounted, comprises a signal line(SL) and a grounding surface(t). The signal line, connected to the output port of the amplification part, transfers a Tx signal outputted from the amplification part. The grounding surface is located below the signal line. On the grounding surface, a pattern part(100) is formed. The pattern part has a bilaterally symmetrical shape with the respect of the signal line.
