Abstract—The geometry of a broadband (0.7–2 GHz) monopole antenna intended to be inserted in a narrow borehole for ground penetrating crosshole application is proposed. The monopole antenna is supposed to be designed on a printed circuit board (PCB) using the low-cost microstrip technology. Based on the FDTD approach, the modeling of the antenna surrounded by its environment has been made, and the influence of several parameters on the radiated waveforms has been studied in details. The modeling of a transmission link has also been considered. Such a study aims at the realization of a narrow broadband antenna. 1.
