A dielectric apparatus applied to building components is disclosed for switching the working frequency of the radio signal passing through the building components and increasing the radio signal's transmittance and the transmission bandwidth. The dielectric apparatus includes a structure body, a filler, and a positioning component. The structure body is made of dielectric materials and includes a chamber. Based on different operating frequencies, the chamber may be filled with the filler made by corresponding dielectric materials to change the operating frequency. The range of the dielectric constant value of the materials used in the structure body and the material for filling the chamber is greater than 1 and less than 200000. The positioning component couples the structure body to a building component to form a composite structure to realize the passage of the specific radio frequency signals and to achieve the effect of enhancing the transmittance.

The present invention relates generally to the field of faraday cages. More specifically, the present invention relates to a carport tent faraday cage device. The device is primarily comprised of a tent body, further comprised of at least one roof frame, at least one wall frame, and at least one door. The tent body is comprised of three layers, an exterior layer, a middle layer, and an interior layer.
