Abstract

A discretely loaded resistive vee dipole is designed and realized for use in pulse radiation applications, such as ground-penetrating radars. The resistive vee dipole is capable of radiating a broadband pulse whose shape is simply related to the input signal. In addition, it mostly eliminates the multiple reflections between the surface of the ground and the antenna because of its low radar cross section. Other investigators have studied the resistive vee dipoles using continuous loading. The antenna presented in this paper is printed on a circuit board and discretely loaded with off-the-shelf surface-mount chip resistors, making it easy, inexpensive to build, and mechanically stable. The characteristics of the antenna on a circuit board are measured and compared with the characteristics of the antenna in free space, which is numerically modeled using the method of moments code. The effects of the balun on the performance of the antenna are also presented.
