摘要： A non-radiative dielectric waveguide coupler for coupling or dividing high-frequency signals between at least two dielectric waveguides arranged maintaining a predetermined gap between a pair of parallel flat conductors, wherein said two dielectric waveguides are connected to each other through a bridge of a dielectric material. Upon joining the two dielectric waveguides through the bridge, the gap between the two dielectric waveguides, that affects the characteristics of the coupler, is set maintaining a high precision without effecting any particular positioning operation. Therefore, the coupler can be mass-produced very favorably. Besides, the gap between the two dielectric waveguides is stably maintained without being varied during the production of the coupler or during the use of the coupler, contributing to improving the reliability of the coupler. A drop in the characteristics of the coupler stemming from the provision of the bridge is easily avoided by setting the width of the bridge to be smaller than the width of the dielectric waveguides.
摘要翻译：一种非辐射介质波导耦合器，用于在布置成保持一对平行扁平导体之间的预定间隙的至少两个介质波导之间耦合或分割高频信号，其中所述两个介质波导通过电介质桥接器相互连接材料。在通过桥连接两个介质波导时，设置影响耦合器特性的两个介质波导之间的间隙保持高精度，而不影响任何特定的定位操作。因此，可以非常有利地大量生产耦合器。此外，两个介质波导之间的间隙在耦合器的制造期间或耦合器的使用期间被稳定地保持而不变，有助于提高耦合器的可靠性。通过将桥的宽度设置为小于介质波导的宽度，可以容易地避免由提供桥提供的耦合器的特性的下降。
