Abstract :
This paper presents a spiral antenna which is located on a conducting cylinder (SPC). The antenna surface is parallel to the cylindrical surface. The authors examine the radiation characteristics of the SPC. The conducting cylinder is approximated using wire grids, and an electric field integral equation is solved with the method of moments. The axial ratio, radiation pattern, and gain are evaluated and discussed.
