如今，现代通信系统依靠高性能设备的设计来增强通信效果，实现高质量的生活和智慧城市系统。作为信号处理的关键步骤，微波滤波去除接收信号中不需要的频率成分，增强有用的频率成分。然而，损耗大、体积庞大、频带单一等缺点极大地限制了其在城市计算中的实际应用。因此，具有双频特性的滤波器对于现代无线通信，如设备对设备通信、环境监测和自动驾驶是非常理想的。本文基于mie谐振超透射理论，设计并制作了一种双频微波滤波器。电磁波不能通过金属薄膜上钻出的亚波长孔传播。通过在两个孔径中加入两个不同尺寸的介电长方体，在10.0-12.0 GHz频率范围内出现两个通带。在此范围内，插入损耗小于0.4 dB， 3db带宽大于48mhz。特别是，两个通频带的频率可以通过调节电介质长方体的大小来调节。该方法为设计可调谐双频微波带通滤波器开辟了一条道路，有利于提高频谱资源的利用率。
Nowadays, modern communication system relies on the designs of high-performance devices to enhance communication effect for a high quality of life and smart city system. As a crucial signal processing step, microwave filter removes unwanted frequency components away from the received signal and enhances the useful ones. However, large loss, bulky size, and single-band greatly limit the practical applications in urban computing. Therefore, the filters with dual-band characteristic are highly desirable for modern wireless communication, such as device-to-device communication, environment monitoring, and automatic driving. In this paper, a dual-band microwave filter is designed and fabricated based on the theory of Mie-resonance extraordinary transmission. An electromagnetic wave cannot propagate through a subwavelength aperture drilled in a metallic film. By adding two dielectric cuboids of different sizes into the two apertures, two passbands appear in the frequency range of 10.0–12.0 GHz. In this range, the insertion loss is less than 0.4 dB, and 3-dB bandwidth is more than 48 MHz. Particularly, the two passband frequencies can be tuned by adjusting the size of the dielectric cuboids. This approach opens a way for designing tunable dual-band microwave bandpass filter, which is benefit for enhancing spectrum resource utilization.
