A one-input four-way power divider is developed for feeding circuit of a microstrip comb-line antenna. The four-way power divider is composed of two-stage tournament-configuration of three Y-junctions. To control the sidelobe level and beam width in radiation pattern of the array, the power dividing ratio is assigned for the four-way power divider. Required dividing ratio is designed by changing the line width to control the impedance. To take impedance matching at the connection parts of the Y-junctions, 1/4-wavelength impedance-transformers are applied to the divider and taper structure is supplied at discontinuities. Four-comb-line antennas are designed and fabricated at 76.5GHz. We evaluated sidelobe level and beam width by experiment to confirm the performance of the power divider.
