This work aims to provide an electrically small reconfigurable antenna with modification in the radiating strip length to switch between 5G mid-band and 4G band-40 application. Initially, the length of the radiating strip is designed to operate at 3.5 GHz for 5G mid-band applications. Using switch configuration, the length of the radiating strip is modified so that the antenna's resonant frequency shifts from 3.5 GHz to 2.32 GHz, which can be operated at 4G band-40. The effective radiation remains the same at two resonant modes. In terms of size, the proposed antenna geometry is (16.5 × 10.5 × 1.6) mm3. The designed antenna with an electrical length of 0.7014 mm is electrically small in size in comparison with the works of literature. Antenna structure provides a gain of 0.69 dBi and 1.35 dBi at resonant frequencies 2.32 GHz and 3.5 GHz, respectively. The geometry of the antenna is straightforward, and the prototype is fabricated on a low-profile FR4 substrate. The simulated results are validated experimentally.

非对称共面带状馈电小型可重构 5G 中频天线

这项工作旨在提供一种电小型可重构天线,可修改辐射带长度,以在 5G 中频和 4G 40 频段应用之间切换。最初,辐射带的长度设计为在 3.5 GHz 下运行,用于 5G 中频应用。使用开关配置,修改辐射带的长度,使天线的谐振频率从 3.5 GHz 偏移到 2.32 GHz,可以在 4G 频段 40 下运行。有效辐射在两种谐振模式下保持相同。在尺寸方面,建议的天线几何尺寸为 (16.5 × 10.5 × 1.6) mm 3. 与文献作品相比,设计的电长度为 0.7014 mm 的天线在电学尺寸上很小。天线结构在谐振频率 2.32 GHz 和 3.5 GHz 下分别提供 0.69 dBi 和 1.35 dBi 的增益。天线的几何形状很简单,原型是在低剖面 FR4 基板上制造的。模拟结果经过实验验证。
