摘要

提出了一种新颖的单单元鹰形和双单元阵列(超宽带)鹰形开槽微带天线。在介电常数为4.4，厚度为1.6 mm, tan δ = 0.02的衬底上设计和制作天线。采用一种新颖的鹰形单平面紧凑型电磁带隙(UCEBG)单元，减少了相同形状阵列单元之间的相互耦合。结果表明，在第一频带(1.71 ~ 2.98)GHz、第二频带(4.26 ~ 5.62)GHz和第三频带(6.57 ~ 9.16)GHz分别实现了6 dB、10 dB和6 dB的互耦降低。利用CST模拟器对微带阵列进行了研究，并在精度为25μm的原型激光机上制作了微带阵列。用NSI公司的700S-30球形近场系统在消声室中测量了辐射方向图。该天线可用于军事或无线应用。

Mutual coupling reduction in UWB slotted antenna array using UCEBG structures for wireless applications

A novel single element Eagle shape, and two element array (Ultra Wide Band) Eagle shape slotted microstrip antennas are presented. The antennas were designed and fabricated on a substrate with dielectric constant of 4.4, thickness of 1.6 mm, and tan δ = 0.02. A novel Eagle shape uni-planar compact electromagnetic band gap (UCEBG) cells are applied to reduce the mutual coupling between array elements with the same shape. The results show that a reduction in mutual coupling of 6 dB is achieved at first band (1.71 - 2.98) GHz, 10 dB at second band (4.26 - 5.62) GHz, and 6 dB at third band (6.57 - 9.16) GHz. The microstrip array was studied by CST simulator and fabricated by proto laser machine with precision 25μm. The radiation patterns are measured in an anechoic chamber with Nearfield Systems Inc. (NSI) 700S-30 spherical near-field system. The antenna can be used in the military or wireless applications.
