Abstract: Wireless Underground Sensor Networks (WUSN) consists of buried sensors nodes which are expected to communicate through the soil. The significantly high attenuation caused by the soil properties is the main challenge for their feasibility. This paper tries to elaborate the design of a compact Wide Band Antenna, which is used as vehicle mounted ground penetrating Radar to identify landmines. The aim of this paper is to design a micro strip patch antenna as a Ground Penetrating Radar operating in the WiMAX band of 3.51 GHz with micro strip feeding. This paper presents the design of Micro strip patch antenna with slot for wide band applications. The micro strip patch antenna with slot have been on FR4 substrate (gr=4.3) with overall size of 40mm x 40mm.The proposed antenna with DGS ground offers excellent wide-band performance ranging from 3.20 GHz to 3.70 GHz. The antenna exhibits bandwidth of 520 MHz. The simulated radiation pattern of micro strip patch has been observed nearly omnidirectional. Such type of antenna can be used for UWB system. This paper also studies the impact of the soil on performances of a new small wide band buried antenna and then analyzes the effect of depth of penetration of the communication link from underground to above ground. This study includes the effect of soil depth. The simulations results show that with short distances underground to above ground UWB wireless communication is possible.
