Background
a base station antenna
Details
Traditionally, solid (non-foamed) plastic materials have been used for base station radomes, but Smart Cellular Board™ realizes increased radio wave permeability and a lower dielectric constant (Dk) and dissipation factor (Df) through the introduction of micro-foam. The lower density will also contribute to reducing the weight of the radome (Fig. 3 and 4). In addition, the excellent forming and machining characteristics make it possible to supply Smart Cellular Board™ in various forms (Fig. 5).
In the high frequency wave band used for Beyond 5G/6G, because the same high frequency signal will pass through the antenna and RF components at the base station, the impact of dielectric loss tends to increase compared to the traditional lower frequency signals. Also, because this dielectric loss will lead to increased heat being generated, the base station will be equipped with large heat sinks for thermal management. In response to these issues, Smart Cellular Board™ minimizes substrate dielectric loss through its excellent dielectric characteristics, and as a result, it will contribute to limiting heat generation from the substrate and reducing the weight of the heat sinks.
We will continue to contribute to the realization of a Beyond 5G/6G society through the development of products that utilize our original technology.
(Note) Dielectric loss = k × f × √Dk × Df (k: Constant, f: Frequency, Dk: Dielectric constant, Df: Dissipation factor)
