%X <p>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 <em>E</em> and <em>H</em>-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.</p>
