具有高隔离度的紧凑型三陷波UWB-MIMO天线设计
Compact triple trap UWB-MIMO antenna design with high isolation
摘要
Abstract
A compact triple trap UWB-MIMO antenna with high isolation is proposed,with overall dimensions of 38 mm×26 mm× 1.2 mm.A high degree of isolation is achieved by loading a modified corrugated T-shaped decoupling structure on the ground plate and etching an inverted"π"slot;a"U"slot is etched on the radiating patch,a class"H"slot is etched on the feed line,and an"H"slot is etched on the right-hand side.By etching a"U"slot on the radiating patch,etching a class"H"slit on the feed line,and introducing an inverted"C"parasitic branch on the right side,trapping in the WiMAX(3.3-3.6 GHz),WLAN(5.15-5.85 GHz)and X-band(7.25-7.75 GHz)bands are achieved.Simulation and test results show that the antenna works in the frequency band of 2.9 to 11.3 GHz(relative bandwidth reaches 118.31％),with isolation less than-22.6 dB,envelope correlation coefficient(ECC)less than 0.01,high radiation efficiency and good radiation characteristics,and the designed antenna can be widely used in the field of wireless communication systems.关键词
