摘要

用于6G中上频段的2 $\,\times \,$ 4双馈封装天线（AoP）支持高功率和双极化，结构紧凑，可用于智能手机和密集多输入多输出（MIMO）基站。双馈天线单元的设计考虑了双线极化和双频工作。因此，所提出的天线可以提供双频，实现32.3% （9.77 GHz至13.45 GHz）的-6 dB阻抗带宽，端口对端口隔离高于-15 dB，包络相关系数小于0.02。制作了用于MIMO天线的2$\,\times \,$ 4天线阵列，用于评估辐射特性。采用垂直探测系统对所设计的天线进行了测量和验证。每个元件测量-6 dB阻抗带宽，低频段超过6.83%，高频段超过4.9%。在10.25 GHz和12.7 GHz下测得的轴向增益分别为6.45 dBi和6.7 dBi，双带宽下测得的包络相关系数均小于0.04。

4 dual-feed antenna-on-package (AoP) for 6G upper midband supports high power and dual-polarization, with a compact structure enabling potential use in smartphones and dense multiple-input–multiple-output (MIMO) base stations. The dual-feed antenna element is designed considering dual-linear polarization and dual-band operation. Consequently, the proposed antenna can provide dual-band, achieving a –6 dB impedance bandwidth of 32.3% (9.77 GHz to 13.45 GHz), port-to-port isolation higher than –15 dB, and the envelope correlation coefficient lesser than 0.02. The 2

4 antenna array for a MIMO antenna is fabricated for the evaluation of radiation characteristics. The proposed antennas are measured and verified by vertical probing system. Each element was measured with –6 dB impedance bandwidth of over 6.83% in low band and 4.9% in high band. The measured gain of boresight is achieved to 6.45 dBi at 10.25 GHz, and 6.7 dBi at 12.7 GHz, and the measured envelope correlation coefficients are all less than 0.04 in the dual-bandwidth.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
