摘要
提出一种紧凑型高隔离度多输入多输出超宽带天线,该天线由两个共面梯形辐射单元背靠背连接在一起构成,衬底材料的相对介电常数为4.4。在两个辐射单元之间放置高隔离金属条,确保天线具有高隔离度。该天线在整个超宽带频带上电压驻波比VSWR为2:1,隔离度高于20 d B,峰值增益为5.2 d Bi,峰值有效率为90%,且包络相关性系数ECC(Envelope Correlation Coefficient)≤0.164 1。
A compact high isolation multiple input and output ultra-wideband antenna was proposed. The antenna was made up of two coplanar trapezoid structures of radiating unit back to back together. The relative permittivity of substrate is 4.4. A high isolation metal strip was placed among two rediating units to ensure the antenna having high isolation. The antenna VSWR is 2：1 on the entire UWB frequency band, and the isolation is higher than 20 dB, the peak gain is 5.2 dBi, the peak effective rate is 90%, and the ECC is less than 0.164 1.
