报告摘要

Next-generation small-satellite platforms require compact, multifunctional antenna arrays that jointly support precise tracking and wideband communication within severe SWaP limits. This report reviews and compares a set of candidate arrays developed for that purpose, including planar monopulse antenna arrays for high-accuracy angle measurement and tracking, shared-aperture wideband circularly-polarized (CP) arrays that enable shared-aperture Tx/Rx, dual-CP antenna array offering broad K/Ka-band coverage, and wideband linearly-polarized (LP) arrays produced by multi-material 3D-printing that emphasize weight reduction and integration. Key enabling technologies comprise sum/difference monopulse networks, aperture decoupling techniques, AR-broadening methods, and additive manufacturing. The synthesis indicates a practical path to Integrated Sensing and Communication (ISAC)-capable for small-sat platforms.
