摘要
研究了圆极化微带贴片天线,通过在普通圆形贴片上开槽,提出了一种结构新颖的圆极化微带贴片天线。仿真以及实测结果表明,该天线具有较宽的3dB波瓣宽度(±50°)和良好的圆极化轴比性能,并且新型微带贴片天线的尺寸要远小于普通的圆形或圆环形贴片天线的尺寸。
In this paper a novel circular-polarized microstrip patch antenna is given based on the study of common circular microstrip patch antenna. This new type of patch looks like common circular patch with some slots. Numerical results and measured data indicate that the new patch antenna has a wide beam and good performance of axial ratio. The radiation pattern of the antenna is very good. Another property of the new patch antenna is that the size of new antenna is smaller than common circular patch or annular patch antenna.
