【摘要】 提出并设计了一种可应用于多频段无线通信的小型化宽带微带贴片天线。天线采用共面容性耦合的馈电方式补偿探针的分布电感,应用FR4高频介质板与空气层组成的层叠介质、E-E形和半E-E形辐射贴片缩减天线的尺寸。结果表明,E-E形微带天线和半E-E形微带天线的阻抗带宽分别为1.85~2.57 GHz(相对带宽32.6%)和1.85~2.50 GHz(相对带宽29.9%)。和普通E形微带天线相比,E-E形和半E-E形微带天线的贴片面积缩小了47%和61%。更多还原

【Abstract】 A compact and wideband microstrip patch antenna for multi-band wireless communications was proposed and designed. The antenna is fed by co-plane capacitive coupling method to compensate the inductance of the feeding probe, using stacked substrate of FR4 and air, an E-E or half E-E shaped radiating patch to reduce the size of the antenna. The results show that the bandwidths of the E-E and half E-E shape microstrip antennas are 1.85~2.57 GHz(relative bandwidth 32.6%) and 1.85~2.50 GHz(relative bandwidth 29.9%), respectively. Compared with ordinary E-shaped microstrip antenna, the area of E-E and half E-E microstrip antenna reducts by 47% and 61% patch.更多还原
