加载电磁带隙反射板的偶极天线系统的阻抗特性
Impedance characteristic of dipole antenna with reflection board of electromagnetic bandgap
摘要
Abstract
The simulation of the dipole antenna system with the electromagnetic bandgap (EBG) was implemented and it was focused on the input-impedance of dipole antenna system especially on the relationship between the input-impedance and the height between the dipole antenna and the EBG reflector board plane.The simulation results show that the input-impedance of antenna system changes with the height between the dipole antenna and the EBG board.Although the real part R of the input-impedance varies with the height,its value is always greater than zero,which means the antenna radiation consumes the electromagnetic energy.The imaginary part of the input impedance of the antenna can be positive or negative,which shows that when the height of electromagnetic bandgap changes,the antenna system can present capacity or induetivity.The electromagnetic bandgap reflection plate resonance occurs at appropriate height,the imaginary part of the input impedance of the antenna is zero and the antenna can effectively radiate electromagnetic waves.关键词
