摘要
提出了一种基于非对称V型槽加载的探针馈电圆极化单层钻石形微带贴片天线。通过调节V型槽的槽宽、槽长、开槽倾角及馈电点位置可实现微带贴片天线的圆极化辐射。研究了V型槽尺寸对微带贴片天线性能的影响。结果表明:介质厚度为0.051λ_0(λ_0为中心工作波长)时,天线的阻抗带宽大于9%(VSWR≤2),圆极化带宽为3%(AR≤3),最大增益可达6.29 d Bi,最小轴比小于0.5 d B。
A new microstrip antenna with asymmetrical V-slotted diamond-shaped patch on a single-layer dielectric and probe feed was proposed. The circular polarization was achieved by tuning the width, the arm lengths, the arm angle of the V-slot and the excitation position. Effects caused by different parameters of the V-slot on the antenna were studied. The simulation results show that about 9% relative impedance band of VSWR≤2 is achieved when the dielectric thickness is about 0.051 λ0 (the center wave length). The 3 dB axial ratio bandwidth of the antenna is 3%. Moreover, the max gain of the antenna reaches 6.29 dBi and the best axial ratio is lower than 0.5 dB.
