Abstract	Antennas footprint is an important parameter for good detection result in ground penetrating radar(GPR) survey. The various condition of soil under which a target is buried may change the footprint of an antenna. An antenna with a capacity to adapt, with different soil condition is therefore needed. This type of antenna is capable of keeping the footprint constant in different soil condition. The footprint of an antenna is related to the antennas dimension. In this paper, Modified dipole array is proposed as an adaptive antenna for GPR. With RF Switch circuit, we choose the element on the antenna that will be fed considering to footprint that will be produced. If coupling between element in the array is significant, the array for GPR application will fail to create its adaptation capability. Resistive loading is used to reduce coupling level between elements in the array.
