摘　　要：本文研究的小型化智能天线,基于微带陶瓷智能天线设计思路,通过引入多重微型结构,明显提高了单阵元辐射效率,从而使得在天线增益接近常规智能天线条件下,天线整体体积缩小到常规智能天线的1/4左右。LTE试验网测试和应用研究表明,目前该小型化智能天线各指标已达到或接近常规大天线水平,已基本具备规模组网试商用能力,在城区、密集城区及建站困难区域有着广阔而良好的应用前景。In this paper, the miniature smart antennas, which based on micro-strip ceramic and multiple micro- structure, significantly improved single-element radiation efficiency, making the antenna gain is close to the conditions of the conventional smart antenna, and the antenna overall volume is reduced to about quarter of the conventional smart antenna. LTE trial network testing and application studies have shown that the performance of the miniature smart antenna has reached the level close to the conventional antenna and has basically met the requirements of commercial trial network. In urban areas, dense urban areas and the establishment of the station difficult areas, the miniature smart antennas have a broad application prospects.
