A conformal antenna design using transformation optics theory

Although the analysis of electromagnetic sources transformation under the theory of transformation optics has been widely discussed in many literatures, there are few discussions about actual antennas in the context of coordinate transformation. In this paper, we deduce the proper feeding formulation which is excited upon antennas according to the transformation method of ideal electromagnetic sources, and validate the analysis through numerical simulation of a specific example. This analysis shows that we can design a conformal antenna which has the same field distribution with the antenna having the desired performance by covering the antenna with transformed media. This method provides a new way in designing conformal antennas.
