摘要
Abstract
A novel dual-band monopole applied in wireless communication is developed,and the antenna is fed by CPW.The size of antenna is only 30 mm×25 mm×0.8 mm,and the substrate is FR4.The antenna is designed based on planar monopole,by adding slots in the ground of CPW,it can work in two bands,and the impedance matching is improved as tapered structure is added in the monopole patch.Numerical simulation on the characters of the antenna is performed with HFSS software.The simulation results demonstrate that the antenna has the radiation features similar to monopole,and has wider bandwidth,S11 is less than -10 dB within 3.01~6.1 GHz,the relative wideband of the antenna is 67.8%,and the operating frequency band can cover 3.5/5.2/5.5/5.8 GHz.Moreover,the antenna has omnidirectional radiation pattern and good radiation gain.It has small size and simple structure,and is easy to be fabricated.Therefore,the antenna can be widely used in WLAN and WiMAX communication system.关键词
