A high-permittivity dielectric material-filled substrate integrated suspended line (SISL) antenna with size reduction is proposed, which provides a novel fixing method for dielectric resonator antenna (DRA). The proposed antenna is based on five substrate layers with two air cavities while the high-permittivity dielectric material is filled with the upper air cavity of the hollowed substrate. So the antenna is self-packaging. The feeding line is on M5 layer and the bottom air cavity affects the resonant frequency much. The expression about the resonant frequencies, the height of the bottom air cavities, and the size of DRA is given. The operating frequency band is from 6.2 to 6.5 GHz and the maximum antenna gain is 6 dBi. In order to reduce the resonant frequency further, a cross strip is added to M2 layer. At last, the impedance bandwidth for | S ₁₁ | < −10 dB is from 5.7 to 6 GHz and the maximum antenna gain is 5.2 dBi.

具有腔体背衬的高介电常数介电材料填充 SISL 天线

提出了一种尺寸减小的高介电常数介质材料填充基板集成悬浮线（SISL）天线，为介质谐振器天线（DRA）提供了一种新的固定方法。所提出的天线基于具有两个空气腔的五个基板层，而高介电常数介电材料填充有中空基板的上空气腔。所以天线是自包装的。馈线在M5层，底部气腔对谐振频率影响很大。给出了谐振频率、底部气腔高度和DRA尺寸的表达式。工作频段为 6.2 至 6.5 GHz，最大天线增益为 6 dBi。为了进一步降低谐振频率，M2层增加了一个交叉条。最后，阻抗带宽为 | 秒 ₁₁ | < −10 dB 为 5.7 至 6 GHz，最大天线增益为 5.2 dBi。
