A miniaturized frequency reconfigurable CPW-fed antenna operating in the UWB, ISM, WiMAX, WLAN, Wi-Fi, C-band and 5G sub-6 GHz frequency bands is proposed here. The wideband CPW-fed triangular patch is made tunable to three triple-frequency bands on demand by connecting it to different serpentine stubs by using PIN diodes. The combination of triangular patch and serpentines introduced overall 8 number of operating bands (2.45, 3.05, 3.3, 4.1, 4.6, 5, 6 and 6.2 GHz) instead of a wideband (3.78–7.08 GHz) generated by triangular patch. The simulation results of the antenna are in good agreement with the measured results. The phenomena of miniaturization and multiband operation along with a wideband are compared with state-of-the-art antennas presented in the literature to highlight the significance and novelty of the proposed antenna. The proposed antenna has its applications in compact and portable devices operating at multiple frequency bands like, cellular phones, Tablets, Wi-Fi devices etc.

本文提出了一种在UWB，ISM，WiMAX，WLAN，Wi-Fi，C频段和5G低于6 GHz频段运行的小型可重构频率的CPW馈电天线。通过使用PIN二极管将宽带CPW馈电的三角形贴片连接到不同的蛇形短截线，可以根据需要将其调谐到三个三频频带。三角形贴片和蛇形的组合引入了总共8个工作频带（2.45、3.05、3.3、4.1、4.6、5、6和6.2 GHz），而不是三角形贴片产生的宽带（3.78–7.08 GHz）。天线的仿真结果与实测结果吻合良好。与文献中介绍的最新天线比较了小型化和多频带操作以及宽带现象，以突出提出的天线的重要性和新颖性。
