Summary:A microstrip patch antenna array with low-side lobe level, high gain and broadband is presented in this paper. A microstrip patch with one parasitical patch is proposed as a radiation element, and the antenna array is composed of 8×8 radiation elements. Then Chebyshev current distribution is used to design the feeding network on H-plane. The simulated results by CST Microwave Studio software indicate that the antenna array working in Ku band has the center frequency of 17.5 GHz and relative bandwidth of 9.3%. Also, the gain is 20dBi and the first side lobe is -20dB. Hence, this antenna array can be utilized in automotive collision avoidance radars systems.
