Abstract
A novel X-band frequency-scanning antenna array fed by a waveguide slow-wave line is designed and implemented.In order to achieve the beam scanning function and reduce the loss of antenna system,the waveguide slow-wave line structure with coupled-slot on the narrow side is used for feed line.At the same time, double-layer microstrip patch antenna is used for radiation element to broaden the bandwidth and reduce the profile and weight of antenna array.Antenna array is simulated by EM simulation software-HFSS,and a pro-totype including 1 6×40 elements is implemented and tested.The results shown that the VSWR of the antenna array is below 1.5 over the operating band,the scan scope is up to 35 degree,and the sidelobe is below -15 dB.关键词
