Quasi-Yagi antenna based on half-mode substrate integrated waveguide feeding

The invention discloses a quasi-Yagi antenna based on half-mode substrate integrated waveguide feeding. The antenna comprises a dielectric substrate (1), an upper metal coating (2) attached to the upper surface of the dielectric substrate (1), and a lower metal coating (3) attached to the lower surface of the dielectric substrate (1). The lower metal coating (3) and the upper metal coating (2) are connected via multiple plated-through holes (4) penetrating through the dielectric substrate (1). The quasi-Yagi antenna based on half-mode substrate integrated waveguide feeding of the invention has the advantages of wide bandwidth and compact structure. 本发明公开种基于半模基片集成波导馈电的准八木天线，包括介质基板(1)、贴覆于介质基板(1)上表面的上金属镀层(2)和贴覆于介质基板(1)下表面的下金属镀层(3)，所述下金属镀层(3)和上金属镀层(2)由穿过介质基板(1)的多个金属化通孔(4)相连。本发明的基于半模基片集成波导馈电的准八木天线，频带宽，结构紧凑。
