摘要:
我们介绍了一款面向宽带光谱成像应用的宽带漏波透镜天线的设计、制备与性能表征。该天线设计工作在300-900 GHz频段。我们将天线直接集成到Al-NbTiN混合MKID(微波动态电感探测器)中,在以350、650和850 GHz为中心的三个频段(覆盖天线全频段)测量了方向图和绝对耦合效率。我们测得全频段的口径效率$η_{ap} \approx 0.4$,其受限于透镜反射。方向图和效率的测量结果均与仿真吻合良好,验证了该亚毫米波长范围1:3带宽的天线可用于未来的片上光谱仪。
英文摘要:
We present the design, fabrication and characterisation of a broadband leaky lens antenna for broadband, spectroscopic imaging applications. The antenna is designed for operation in the 300-900 GHz band. We integrate the antenna directly into an Al-NbTiN hybrid MKID to measure the beam pattern and absolute coupling efficiency at three frequency bands centred around 350, 650 and 850 GHz, covering the full antenna band. We find an aperture efficiency $η_{ap} \approx 0.4$ over the whole frequency band, limited by lens reflections. We find a good match with simulations for both the patterns and efficiency, demonstrating a 1:3 bandwidth in the sub-mm wavelength range for future on-chip spectrometers.
