摘要
Abstract
A circularly-polarized antenna array composed of sequential rotated circularly-polarized patches is presented ,which can be used in satellite communication in V-band .The axial ratio under beam scanning can be optimized by adjusting excitations of elements ,which guarantees the availability of the antenna in wide scan angle .The design is verified using an 8 × 8 antenna array in the planes of φ=0°and φ=45° . Simulation results show that within 60° the optimized axial ratio of given scan angle can be 0 dB .When the scan angle is 60° ,the realized gain ,side lobe and back lobe achieve 18.7 ,-22.3 and -12.0 dB sepa-rately ,with 4.0 ,2.4 and 10.1 dB higher respectively than the results of antenna composed of sequential ro-tated linearly-polarized patches .The excellent antenna performance in wide scan angle makes the antenna a good choice for satellite communication .关键词
