Abstract
In this work, an artificial magnetic conductor (AMC) ground is designed with a wide zero-phase reflection bandwidth, then a bandwidth-enhanced phased array with a wide-angle scan is realized by mounting a dipole on the AMC. The equivalent circuit analysis is used to broaden the AMC bandwidth, and the image theory is adopted to explain the wide-angle scanning principle. Simulated results indicate that the designed phased array supports a wide scan up to 60 in an active reflection band of 6.79 ~ 9.59 GHz and up to 65° in an active reflection band of 6.88 ~ 9.05 GHz, respectively.
