一种新型宽频带全向天线的设计
Design of a novel broadband omnidirectional antenna
摘要
Abstract
The omnidirectional antennas have been widely used in the next generation of wireless communication systems.A novel cross feed broadband omnidirectional antenna is presented in this paper.The wideband is realized by adding the bulun and wider dipole.Two elements are cross-fed by parallel broadside coupled lines to actualized impedance match.Theoretical analysis of dipole and simulation results with HFSS and measurements of the antenna show that the antenna fabricated on the substrate with thickness of 1.5 mm and relative permittivity of 2.6 can achieve an impedance bandwidth of 44.7% for VSWR<2.The far-field radiant characteristics are good.The out-of-roundness is less than 2.3 dB and the gain is higher than 1.6 dB.The antenna is simple in structure and easy to fabricate,and it has a wide application.关键词
