Abstract

Abstract The future of 5G New Radio development has many significant concerns. We present and investigate a frequency-reconfigurable antenna based on a PIN diode to overcome the working frequency band issue. The dimensions are 30 mm × 20 mm × 1.6 mm, built on material substrate (FR-4) with a relative permittivity of ε r {\varepsilon }_{{\rm{r}}} = 4.4. Two switches allow frequency reconfiguration in the antenna, giving us three operation modes. The design in mode 1 (SW1 = Off and SW2 = Off) covers a 4.6 GHz band. The proposed design in mode 2 resonated at 2.7 and 4.8 GHz (SW1 = On, SW2 = Off or SW1 = Off, SW2 = On), while the design in mode 3 operated at 3.6 GHz (SW1 = On, SW2 = On). Before fabrication, the proposed design is simulated by the Computer Simulation Technology microwave studio software. The presentation and discussion of the radiated pattern and S parameter demonstrate the practicability of the proposed design. The design module’s dimensions and performance are both precisely appropriate. The results indicate a good agreement between both simulation and experimental findings.

基于PIN开关的频率可重构天线的设计与实现

未来5G新无线电的发展有许多重要的关注点。为了克服工作频带问题，我们提出并研究了一种基于PIN二极管的频率可重构天线。尺寸为30mm × 20mm × 1.6 mm，建立在材料衬底(FR-4)上，相对介电常数ε r {\varepsilon}_{{\rm{r}}} = 4.4。两个开关允许天线的频率重新配置，给我们三种操作模式。模式1 (SW1 = Off, SW2 = Off)下的设计覆盖4.6 GHz频段。模式2下的设计谐振频率为2.7和4.8 GHz (SW1 = On, SW2 = Off或SW1 = Off, SW2 = On)，而模式3下的设计谐振频率为3.6 GHz (SW1 = On, SW2 = On)。在制作之前，采用计算机仿真技术微波工作室软件对所提出的设计进行了仿真。辐射方向图和S参数的给出和讨论表明了所提设计的实用性。设计模块的尺寸和性能都是非常合适的。仿真结果与实验结果吻合较好。
