Abstract :
A broadband conformal phased array system with a vaulted geometry is presented in this paper. The system includes a conformal antenna array with a sector cross section. Furthermore, a conformal radome is integrated with the antenna array. The structure of the system is described. The measured bandwidth of the antenna array exceeds 20% (VSWR<;1.5). Also, the scan characteristics of the system are measured and presented. The maximum sidelobe levels (SLLs) are lower than -25dB within the scan range of ±50°.
