Abstract
An S band circularly polarized phased-array antenna was designed, which was realized by arranging and properly rotating 9 microstrip-patch antenna units. Through simulation by HFSS software, in case of 10 dBW radiation power, the phased-array antenna’s EIRP can be larger than 15 dBW in any azimuth of 360o with the large scanning angle of ±80o. Meanwhile, the simulated axial ratio of normal direction is flat in the working band and lower than 0.5 dB. The antenna was assembled and measured. Results show that EIRP is larger than 15 dBW in all the scanning range. Meanwhile, the measured axial ratio of normal direction is flat and lower than 1 dB in the working band. All the measured data matches well with the simulation.关键词
