改善隔离度的“V”型结构的超宽带天线设计与实现
Ultra-Wideband V-shaped antenna design and implementation
摘要
设计了一款栅栏形式的“V”型结构超宽带多入多出(MIMO)天线，将对角线上的2 个基本天线单元置于介质板的另一侧，并引入一种栅栏形式“V”型结构的耦合器来降低天线单元间的耦合，用于改善天线的隔离度。该天线工作频段为3.3~12.02 GHz。经过对回波损耗和隔离度的仿真和测试，证明该款MIMO 天线在不影响超宽带(UWB)天线基本性能的基础上满足了MIMO 天线对隔离和分集增益的要求。
Abstract
An Ultra-Wideband(UWB) Multiple-Input Multiple-Output(MIMO) antenna improving isolation degree is designed and discussed. Two basic antenna units in diagonal layout are located at the other side of dielectric-slab. A kind of V-shaped coupler with the style of fence is introduced to reduce the coupling between antenna units. The working frequency band of the MIMO antenna is from 3.3 GHz to 12.02 GHz. The proposed MIMO antenna meets the requirements on isolation and diversity gain through simulation and testing.
