Design of four-way power-divider to control sidelobe level of microstrip comb-line antenna

摘要

The four-way power divider is designed for the feeding circuit of the four-line comb-line antenna. The dividing ratio of the power divider is controlled by changing the line width. Reflection characteristic of the power divider is improved by using taper structures. The four-way power-divider is developed for low return loss and required radiation pattern.
