Summary:
Conformal antenna has several advantages: less influence on platform’s aerodynamic factor, less space for installation, large scan range and so on. In the past twenty years, conformal antenna has promoted the development of commercial and military application. For instance, satellite communication [1], mobile communication and public safety [2] etc. However, when the classic antennas are used to design conformal ones, it is inevitable to find that the characteristics of antennas would change due to the effect of the platform. Taking patch antenna as an example, to design a conformal patch antenna by using original empirical equation is not appropriate in most condition. So that designing and optimizating the conformal antenna would become a formidable task. In order to solve this problem, space mapping is adopted to optimize the conformal antenna. Space mapping algorithm is firstly introduced by Jone W. Bandler for microwave circuit optimization [3]. With the development of theory of space mapping, more and more effective methods [4, 5] have been proposed. Furthermore, the application of space mapping has expanded its application area into antenna [6]. However, there is little report about conformal antenna design by using space mapping. In this paper, it is represented that an array consisted by three E-patch elements which are aligned along the cone’s generatrix (shown in Fig. 1). And its operating band is from 12GHz to 18GHz (|S11|<-10dB). Simulation results show the result of optimization.
