摘要
近地轨道(LEO)移动卫星通信(sat - com -on- move)技术的不断发展推动了低成本、低姿态用户终端的设计。本文提出了一种宽带双脊波导天线的初步结果，该天线将进一步集成到移动用户终端阵列天线中，工作在ku波段(10.75 - 14.5 GHz)。提出了一种覆盖ku波段的2×2子阵列的设计，其效率在70%以上，以后可以用作更大阵列中的单元电池。设想用3d打印技术制造，以评估该设计的性能。
3D-Printed Double-Ridged Waveguide Array Antenna targeting High-Efficiency Ku-band SatCom on The Move Applications
On-going research about Low Earth Orbit (LEO) mobile satellite communications (Sat-Com-on-The-Move) push towards the designs of low-cost and low-profile user terminals. This paper proposes initial results about a wideband double-ridged waveguide antenna to be further integrated in a mobile-user terminal array-antenna, operating in Ku-Band (10.75 – 14.5 GHz). The design of a 2×2 sub-array covering the Ku-band with an efficiency above 70% is proposed to be later used as a unit cell in a larger array. Fabrication with 3D-printing technology is envisaged in order to assess the performance of this design.
