摘要

研究了一种适用于多输入多输出(MIMO)应用的空腔背平面缝隙天线。在地平面上蚀刻两个槽形天线元件，并采用微带馈线技术对这两个元件进行馈电。该设计使用SIW技术构建，以获得所提出的MIMO天线元件之间的最佳隔离。数值分析表明，该天线工作在7.96 ~ 8.03 GHz的阻抗带宽范围内，S11在-10 dB以下，在8 GHz时隔离度高，小于-21 dB。辐射效率约为70%，在8ghz时实现增益大于4.7 dBi。与传统天线相比，该天线具有良好的辐射性能，包括重量轻，易于制造，适用于MIMO-RADAR系统。

MIMO Cavity Slot Antenna Based on Substrate Integrated Waveguide Technique

A cavity-backed planar slot antenna for multiple-input multiple-output (MIMO) applications is studied in this paper. Two slot antenna components are etched on the ground plane and the microstrip-line feeding technique is used for the two elements. The design is constructed using a SIW technique to obtain the best isolation between the elements of the proposed MIMO antenna. The numerical analysis demonstrates that the antenna works at an impedance bandwidth of 7.96–8.03 GHz for | S11 | less than -10 dB with high isolation reaching less than -21 dB at 8 GHz. With a radiation efficiency about 70% and a realized gain more than 4.7 dBi at 8 GHz. The proposed antenna exhibits good radiation performances comparing to the conventional one, including light-weight, and ease fabrication, which makes it appropriate for MIMO-RADAR systems.
