For miniaturizing a mobile ground penetrating radar (GPR) antenna assembly, an electromagnetic band gap (EBG) structure to reduce the transmitting and receiving cross-talk is proposed. The antenna assembly works around 2.45 GHz and supposed to detect motions though concrete and other building materials. Dimension of the required EBG-structure for both air-coupled and ground-coupled scenarios are analytically estimated. Finite element method based radio frequency simulations are conducted to verify the estimations and to find the optimal dimensions.
