在这封信中，一个紧凑的双频带通滤波器的无线局域网（WLAN）的操作。该滤波器由两个对称的部分组成，整体尺寸仅为0.04 λ 0 × 0.09 λ 0。在每个部分中，两个相对的钩形带不同的谐振路径被用来实现双频工作在2.4和5.8 GHz，分别为19.54%和15.12%的分数带宽。通过调整挂钩的尺寸，可以独立地控制两个通带的中心频率。为了验证所提出的想法，实现了一个原型，测量结果与全波电磁模拟响应吻合良好。
In this letter, a compact dual-band bandpass filter is presented for wireless area networks (WLAN) operations. The filter, which is only 0.04 λ0 × 0.09λ0 in overall dimensions, is composed of two symmetric parts. In each part, two opposite hook-shaped strips with different resonant paths are used to achieve the dual-band operation at 2.4 and 5.8 GHz, with 19.54% and 15.12% fractional bandwidth, respectively. The central frequencies of the two passbands can be controlled independently by adjusting dimensions of the hooks. To verify the proposed idea, a prototype is implemented, and the measurement results agree well with the full-wave electromagnetic simulated responses.
