Indonesia is a country with high earthquake potential, and the disaster caused many victims. The process of searching for victims also took days because of difficulties in finding the victims who were mostly hit by collapsed buildings. Wireless communication technology has become a basic requirement along with technological developments, and wireless communication devices require antennas to communicate in order to be applied in various fields of life, one of them is disaster management. To speed up the process of finding victims, Ground Penetrating Radar (GPR) technology can be used. This paper proposes the design of a multiband antenna capable of operating in five frequency ranges (penta-band antenna) that can be used for various applications such as cellular, WLAN, Bluetooth, GPS, and radar, including GPR. The simulation results demonstrated the proposed antenna design has five resonant frequencies, 2.4-2.6 GHz, 3.1-3.5 GHz, 3.9-4.1 GHz, 5.3-8.3 GHz and 9.6-9.9 GHz with gain from 2.564 to 4.294 dB.
