摘要：
In this paper, we design a Rotman lens working in the UWB band (3.1-10.6 GHz) and investigated the frequency domain and time-domain performance. The lens is designed for a scan angle range of -30 to 30 degrees with six beam ports and eight array ports. The designed lens is loaded with power dividers to improve its broadband performance. The time-domain performance evaluated includes energy patterns, fidelity patterns, and energy correlation patterns. The measured results show that the worst fidelity in the beam direction can also reach 0.958 verifying that the designed lens has good pulse fidelity characteristics.
