The Intense pulsed Electromagnetic field can treat melanoma cells. This way of treating cancerous cells ensures very less radiation on the normal part of our body. In this work the tapered arm Impulse Radiating Antenna (IRA) is designed with high gain. The IRA with tapered feeding arms located at the position of φ=60° gives an average gain improvement of 14% with traditional IRA.Its Electric field distribution has a 3dB beam width of 2 cm and 1cm along lateral and axial direction respectively. The electric intensity radiated by the antenna is 25kV/cm for the input of 130kV. The abnormal skin model is defined and the effect of application of the picosecond pulse is studied at elevatedtemperature.The temperature at the tumor location is 1.8% higher than the nearby tissue for an input of 1 V.
