Abstract
Building materials with metal may serve as electromagnetic shields and deteriorate the transmissions of wireless LAN in residences. To improve the transmissions at a low cost, a conducting wire processed as an inverted-L antenna is attached to a very small hole in the electromagnetic shield. The optimal shape of the conducting wire was found to be 10 mm vertically from the mounting surface and 25 mm at right angles from its tip, as well as its characteristics as an antenna. In addition, the guideline for the installation location based on this experimental result can be considered.
期刊介绍：
The Architectural Institute of Japan’s Journal of Structural and Construction Engineering aim to pursue theories for building and maintaining pieces of architecture as well as the cities or areas surrounding them, and to accumulate and systematize the knowledge needed to put those theories into practice. The Journal of Structural and Construction Engineering focuses on research results in the specific fields of “building materials and construction” and “structures.” Accordingly, it compiles articles in the following areas, disseminates relevant information, and hosts discussions: ・Concrete, steel, and inorganic materials ・Timber and organic materials ・Finishing materials ・Construction and quality management ・Applied mechanics ・Loads and reliability on structures ・Building foundations ・Timber structures ・Steel structures ・Reinforced concrete structures ・Shell and spatial structures ・Engineering seismology and structural dynamics ・Other composite structures
