在这封信中,我们提出了一种新的E面矩形波导弯曲,可以使用分块制造微加工。90°弯曲是通过加工两个线性通道并在外角留下凹口来创建的。该凹口显著地改善了弯曲的回波损耗和插入损耗。该技术的主要优点是它产生紧凑的波导弯曲,从而最小化波导电路的尺寸和传导损耗。另一个优点是,该技术仅需要加工线性通道,因此可以在不需要计算机数控(CNC)铣床的情况下制造。使用电磁仿真软件优化了该波导弯曲的性能,并且发现在波导的整个操作带宽上的最佳反射系数低于-28 dB。然后,使用在微波(12-18 GHz)和毫米频率(140-220 GHz)下测试的两个实验原型来验证模拟设计。
In this letter, we present a new E-plane rectangular waveguide bend that can be micromachined using split-block fabrication. The 90° bend is created by machining two linear channels with a notch left in the outside corner. This notch significantly improves the return loss and the insertion loss of the bend. The primary advantage of this technique is that it produces a compact waveguide bend, minimizing both the size and the conduction loss of the waveguide circuit. Another advantage is that this technique only requires linear channels to be machined, thus it can be fabricated without requiring a computer numerically controlled (CNC) milling machine. The performance of this waveguide bend was optimized using electromagnetic simulation software, and the optimal reflection coefficient was found to be below -28 dB across the entire operational bandwidth of the waveguide. The simulated design was then validated using two experimental prototypes that were tested at microwave (12-18 GHz) and millimeter frequencies (140-220 GHz).
