提出了一种基于柴堆电磁带隙（EBG）材料的W波段高方向性毫米波天线。采用陶瓷挤压自由成形技术，以高纯氧化铝粉末为原料，制备了木堆型EBG结构。所设计的天线可以实现窄波束，而无需使用阵列。测得的半功率束宽分别为14度和10度的E-平面和H-平面。测量结果与模拟结果相比较，
A high directivity millimetre-wave antenna based on woodpile electro-magnetic bandgap (EBG) material at W-band is presented. The woodpile EBG structure is fabricated using the ceramic extrusion freeforming technique with high purity alumina powder. The designed antenna can achieve a narrow beam without using an array. The measured half power beam widths are 14deg and 10deg for E-plane and H-plane, respectively. Measurements results are good compared with simulations
