摘要：
The design of a planar dual-band wide-scan phased array is presented. The array uses novel dual-band comb-slot-loaded patch elements supporting two separate bands with a frequency ratio of 1.4: 1. The antenna maintains consistent radiation patterns and incorporates a feeding configuration providing good bandwidths in both bands. The design has been experimentally validated with an X-band planar 9 x 9 array. The array supports wide-angle scanning up to a maximum of 60 degrees and 50 degrees at the low and high frequency bands respectively.
