| 摘要: |
| 提出一种带有短路销钉的紧凑型电磁带隙结构微带天线，并与相同尺寸的普通短路销钉微带天线作比较。测试结果表明，该电磁带隙结构天线在增益上增加了3dB,H面的交叉极化有了明显的改善。同时也证明了设计具有同样谐振频率的电磁带隙结构单元，使用这种紧凑型结构的单元尺寸仅为普通结构的40%～50％。这对最终实现电磁带隙结构微带相控阵天线具有重要意义。 |

| Abstract: |
| A micro-strip shorted patch antenna with a compact electromagnetic band-gap structure (CEBG) is presented and a performance comparison is made with the conventional short-patched device of identical dimensions. Measured data shows a gain improvement of 3dB and a significant reduction cross polarization for the CEBG antenna. Meanwhile it proves that the design of the same resonant frequency can be attained under such a condition that the CEBG structure cell size is only about 40%～50% of conventional structure. It indicates that the suggested condition is significant in realizing the array of EBG of micro-strip phased antenna. |
