一种相位中心稳定的微带天线设计

Design of microstrip antenna with stable phase center

文中介绍了一种相位中心稳定的微带天线,采用多点均匀馈电设计,通过均匀对称馈电来改善相位方向图的周向对称性,使用有限积分法仿真分析的结果显示此种结构微带天线能达到相位中心离散度小于1mm。

New design of a microstrip antenna with n-point symmetrical feed for stable phase centers is presented in this paper. Uniform symmetrical feed can improve the circumferential symmetry of the phase direction pattern. The result of the emulation analysis using the finite integral method suggests the microstrip antenna of this structure is able to reduce the dispersion of the phase centers to less than 1 millimeter.
