Abstract
According to the manufacturing difficulty of MMW slotted waveguide longitudinal array antenna, the antenna parameters are designed accurately by optimizing whole design method, extracting impedance data of coupling slots, etc. Then, we used the equivalent circuit of slotted array antenna, and obtained parameters with electromagnetic field simulator HFSS. When the slots ware in resonance, the admittance and impedance could be extracted, and then we got the relationship between the offset and the angle of inclination with resonant slot length. On this basis, a method is presented for designing the large waveguide slot array antenna. From the model of HFSS and material object, theoretical results obtained were identity with the experimental values.
