摘要

提出了一种应用于5G n78频段的基于基板集成悬吊线(SISL)平台的滤波天线。天线具有分段馈线、刻蚀具有双i型槽的矩形驱动贴片和在两侧边缘具有凹槽的方形堆叠贴片。蚀刻槽和堆叠贴片引入了两个新的共振频率，增加了带宽。此外，蚀刻槽在低频激发一个深辐射零，叠加的贴片与驱动贴片耦合在高频产生两个深辐射零。三个辐射零点使天线具有高选择性。滤波天线工作在3.2-3.89 GHz，可应用于5G (n78, 3.3-3.8 GHz)频段。带内峰值增益可达9.21 dBi，带外抑制电平高于18.47 dB。

A Filtering Antenna with Slots and Stacked Patch Based on SISL for 5G Communications

A filtering antenna based on the Substrate Integrated Suspended Line (SISL) platform applied for the n78 band of 5G is presented in this paper. The antenna has a segmented feed line, a rectangular driven patch etched with a double I-slot, and a squared stacked patch with grooves at the edges of both sides. The etched slots and the stacked patch introduce two new resonance frequencies increasing the bandwidth. Furthermore, the etched slots excite a deep radiation null in the low-frequency band, and the stacked patch coupled with the driven patch produces two deep radiation nulls in the high-frequency band. Three radiation nulls enable high selectivity of the antenna. The filtering antenna works at 3.2–3.89 GHz, which can be applied to the 5G (n78, 3.3–3.8 GHz) frequency band. The peak gain in the band can reach 9.21 dBi, and the out-of-band suppression levels are higher than 18.47 dB.
