本文研究了一种基于间隙波导（GW）技术的半模波导快速成型技术。为了演示目的，我们设计并测量了两个器件：一个功率分配器和一个弯曲波导。这两种装置都是由两个非接触的金属片构成的。这两款设备也遵循相同的设计过程。在底部，一个水平极化槽GW （GGW）被安置。槽的高度约为一半，这是传播基模所需的。顶盖是一个均匀的固定表面，作为一个高阻抗表面（HIS）在下面的凹槽。功率分配器和弯曲波导在目标带宽（28-31 GHz）内的反射系数测量值均小于- 15 dB，与仿真结果非常吻合。这些设备因其易于制造而脱颖而出，并为大规模生产的更便宜、更坚固的GW设计开辟了道路。
In this letter, a half-mode waveguide based on gap waveguide (GW) technology for rapid prototyping is explored. Two devices have been designed and measured for demonstration purposes: a power divider and a curved waveguide. Both devices are constructed from two noncontacting metal pieces. Both devices also follow the same design process. In the bottom piece, a horizontally polarized groove GW (GGW) is housed. The height of the groove is about half, which is required to propagate the fundamental mode. The top cover is a uniform pinned surface that acts as a high impedance surface (HIS) over the groove below. Both the power divider and the curved waveguide show measured reflection coefficient values of less than −15 dB in the bandwidth of interest (28–31 GHz) and are in excellent agreement with simulated results. These devices stand out for their ease of fabrication and open a horizon for cheaper and more robust GW designs for mass production.
