Abstract
This paper presents a directional bow tie patch antenna for ground penetrating radar (GPR) applications. There are four
proposed designs for this paper. Three of the antenna is designed by introducing Sierpinski gasket fractal concept on
bow tie patch antenna. There is some modification on this design in order to create a new different fractal design that is
applicable for GPR applications. The bow tie antenna performance is studied across 1 GHz to 4 GHz. The best return loss
obtained for this paper is at 3.7 GHz where all four designs have its best performance. The comparison at 3.7 GHz of
these four antenna designs presented in this pape
