Abstract :
In this paper, a directional bow-tie antenna for EMI measurements was proposed. For obtaining the directionality, two backward edges of each half element were straight-line, and two slits were placed on the elements to suppress the sidelobe level. The reflection coefficient less than -4 dB between 300 and 870 MHz and front to sidelobe ratio of 9.0 dB were measured at 870 MHz.
