3D model of antenna system embedded into building envelope for improved cellular signal transmission through load-bearing walls

The purpose of this dataset is to supplement the data presented in our journal publication "Analyses of Distributed Antennas Embedded into a Load Bearing Wall for Improved Signal Penetration" (see https://arxiv.org/abs/2207.06185). This dataset contains the 3-D discretized model, without the internal numerical mesh, of the unit cell of the spiral antenna system embedded in a load bearing wall. The 3D model is in .STP format (see ISO 10303-21:2016), which can be imported into most commercial computer-aided design (CAD) software. The wall's dielectric properties are calculated using the model described in ITU-R P.2040-2 (https://www.itu.int/rec/R-REC-P.2040/en, material parameter and calculation model are on pages 22-23). Materials used in the antenna system and their electrical and thermal parameters are given in the file materials.txt
