本文提出了一种基于间隙波导技术的半模波导，用于快速成型。为演示目的设计了一个功率分配器。功率分配器由两个不接触的金属片构成。水平极化功率分配器安装在底部。槽的高度大约是传播基模所需的高度的一半。顶盖是一个均匀的固定表面，作为底板槽上的高阻抗表面（HIS）。模拟的反射系数显示，在感兴趣的带宽（28至31 GHz）范围内的值小于-15 dB。这种设计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 communication, a half-mode waveguide based on Gap Waveguide technology for rapid prototyping is presented. A power divider is de-signed for demonstration purposes. The power divider is constructed from two non-contacting metal pieces. The horizontally-polarized power divider is housed in the bottom piece. The height of the groove is about half that which would be 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 of the bottom plate. The simulated reflection coefficient shows values of less than -15 dB in the bandwidth of interest (28 to 31 GHz). This design stands out for its ease of fabrication and opens a horizon for cheaper and more robust GW designs for mass production.
