This paper presents the design of optimum miniatureized conformal smart antenna system using 1×8 switched Butler Matrix and the realization of its planar smart antenna system. The demands of wireless communication were increases, so the higher capacity, wider coverage and low attenuation are main characteristic to provide the better and quality services. Smart antenna systems provide a broad range of ways to improve the performance of wireless system through the increase of the number of voice calls and the amount of data throughput, to avoid interference and to ease network management. The proposed both planar and conformal smart antenna system structures radiation characteristics are obtained to demonstrate the excellent performance which has isolation up to -27 dB and coupling up to -52 dB with antenna return loss equals to -37 dB to meet the requirements for wireless communications applications.
