- 摘要:
- 设计一个输入阻抗可调的微带偶极子天线,该天线谐振频率为3.5 GHz,由两个对称的辐射单元和加载在馈电端口处对称的阻抗调节枝节组成。通过调节两个枝节的长度,可以实现天线的电感性或电容性的输入阻抗特性。天线采用柔性基板,能够弯曲,可以贴附于弧形物体表面。结果显示弯折程度对天线性能有一定的影响。由于该天线的这些特性,使其能适用于5G系统。
- Abstract:
- A microstrip dipole antenna with adjustable input impedance is designed, which resonates at 3.5 GHz and consists of two symmetrical radiating units and symmetrical impedance-adjusting branches loaded at the feed port. By adjusting the length of the two branches, the inductive or capacitive input impedance characteristics of the antenna can be achieved. The antenna uses a flexible substrate that is capable of bending and can be attached to curved object surfaces. The results show that the degree of bending has an effect on the performance of the antenna. These characteristics of the antenna make it suitable for use in 5G systems.
