摘要：

设计了一种埋藏介质贴片引向天线，工作在2.4 GHz的无线工业、科学、医学频段，该天线采用金属片与介质板层叠安放，辐射方向垂直于天线表面，属于端射天线.嵌入了超材料结构，剖面结构尺寸缩小为原天线的69%.同时，天线匹配性能有所提升，辐射特性优于原天线.采用有限元全波仿真技术对天线的设计进行了分析和优化，改进后的天线在2.4 GHz频点回波损耗下降了3 dB，E面和H面辐射场强提升了1 dBi，实现了天线的小型化和灵活性.最后通过时域有限积分法对辐射性能进行了验证.

Abstract:

Working in the 2.4 GHz wireless industrial scientific medical (ISM) band, a buried dielectric patch Yagi antenna was designed. Antenna metal sheet and medium plate is placed alternately and radiate perpendicular to the antenna surface, belonged to the end-fire antenna. The antenna is improved by embedded metamaterial structure. By using the phase compensation characteristics of metamaterial,the section size shrinks to 69% of the original antenna structure, at the same time, the matching and radiation performance is better than that of original antenna. A full-wave finite element simulation method was adopted to design and analyze the antenna, and the improved antenna return loss is decreased by 3 dB in 2.4 GHz frequency, and then E and H-plane radiation field intensity is got 1 dBi, which achieves the small size and flexibility demand of the antenna. Finally, the time domain finite integration method verifies radiation performance.

Key words: metamaterial, yagi antenna, buried dielectric patch, backward wave
