摘要：
Aperture coupling feed and double-layer microstrip patch structure are applied to design microstrip antenna element and subarrays of microstrip antenna array with high gain low sidelobe and backlobe at Ku-band. Parallel feed and T-junction type power divider are used to design low sidelobe array by the principle of Dolph-Chebeshev distribution. The simulate results show that the relative bandwidth of the element (VSWR <= 1.5) reaches 25.6%. From the measurement results of subarray: the operational bandwidth (VSWR <= 1.5) are not less than 0.96GHz and the gain are about 24dB, which are in good agreement with the simulate results. The 256 elements microstrip antenna array with sidelobe in E-plain is simulated.
