Abstract

Nowadays, MIMO technology is one of the hot issues in the development of communication technology. The power dividers have a large role in microwave circuits and it is very important in antenna array systems. This letter presents a broadband eight-way power divider based on the Wilkinson power divider for MIMO communication systems. The power divider is composed of a radial cavity equipped with coaxial probes serving as the power divider circuits, along with microstrip lines loaded with resistors that function as the isolation network. By combining these two parts, the power divider achieves more than 25% operating bandwidth with a theoretical 22.5 dB port isolation. Experimental verification for a C-band (5.8–7.3 GHz) broadband eight-way power divider is presented. Measured results show that the output return loss is better than 18 dB, the isolation is better than 20 dB, and the insertion loss is within 9.03±0.25 dB.

用于 MIMO 通信系统的低插入损耗宽带八路高隔离腔体功率分配器

如今，多输入多输出（MIMO）技术是通信技术发展的热点问题之一。功率分配器在微波电路中发挥着重要作用，在天线阵列系统中也非常重要。本文介绍了一种基于威尔金森功率分配器的宽带八路功率分配器，适用于 MIMO 通信系统。该功率分配器由一个径向腔体和作为功率分配器电路的同轴探针，以及作为隔离网络的装有电阻器的微带线组成。通过将这两部分结合在一起，功率分配器可实现超过 25% 的工作带宽和 22.5 dB 的理论端口隔离度。本文介绍了 C 波段（5.8-7.3 GHz）宽带八路功率分配器的实验验证。测量结果表明，输出回波损耗优于 18 dB，隔离度优于 20 dB，插入损耗在 9.03±0.25 dB 范围内。
