为了KSTAR的高效电流驱动，正在考虑升级到高场侧(HFS)或顶部发射器上的低混合电流驱动(LHCD)系统。HFS或顶部发射器需要紧凑，因为内侧和上部偏滤器附近的空间狭窄和拥挤。本文介绍了紧凑型LHCD天线的研究进展，简要回顾了行波天线的冷模，并与新设计的谐振型缝隙波导阵和无源有源多结相结合的SWA PAM进行了比较。行波天线结构简单，而SWA PAM具有N||调节能力。
Upgrading to a lower hybrid current drive (LHCD) system on the high field side (HFS) or top launcher is under consideration for efficient current drive of KSTAR. The HFS or top launcher needs to be compact because of the tight and congested space at the inboard and near the upper divertor. This paper introduces a study of compact LHCD antenna development, and includes a brief review of a traveling wave antenna cold model and comparison with the new design of a resonant type slotted waveguide array in combination with a passive active multijunction, i.e. SWA PAM. The traveling wave antenna has structural simplicity, while SWA PAM has N||adjustment capability.
