Abstract :
Sidelobe suppression of the alternating-phase fed array in the E-plane is discussed. The T-junctions for the alternating-phase fed waveguide array are designed for Taylor pattern with sidelobe level of -25dB. The validity of the design of the power divider consisting of T-junctions for sidelobe suppression is confirmed.
