ABSTRACT
We apply the theory of transformation electromagnetics to source arrays and show that a complex conformal antenna array can be made to behave like a geometrically different array when surrounded with a properly designed transformation electromagnetics medium. Numerical simulations are presented to show how a nonuniform circular array can be made to radiate and receive as a uniformly spaced linear array. In this way, transformation electromagnetics provides a method by which all of the advantages of simple arrays in array processing, such as beamforming, can be retained in an array whose elements are constrained to a complex geometry.

    This paper analyzes the change of VSWR and radiation performance when the smart antenna element doesn't work. From the analysis, it is found that the damage of the antenna element has great influence on the broadcast beam, and it's not enough to just depend on the detection of VSWR. Traditional...
