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...
Aperture coupling feed and double-layer microstrip patch structure are applied to design microstrip antenna element, 64 elements and 256 elements microstrip antenna array. Parallel feed and T-junction type power divider are used to design antenna array. The measured results of subarray antennas show that the operational bandwidth (VSWR les 1.5) is 1.32 GHz and the gain is not less than 24 dB which...
