ANTENNA PROTECTION STRUCTURE, ANTENNA MODULE INCLUDING SAME, COMMUNICATION DEVICE, COMMUNICATION BASE STATION, AND METHOD FOR MANUFACTURING ANTENNA PROTECTION STRUCTURE

摘要

A housing as an example of an antenna protection structure (50) is provided with a first dielectric layer (51), a second dielectric layer (52) laminated on the first dielectric layer (51), and a third dielectric layer (53) laminated on the second dielectric layer (52). The relative electric permittivity of the second dielectric layer (52) is greater than the relative electric permittivities of the first dielectric layer (51) and the third dielectric layer (53). The thickness of the second dielectric layer (52) is less than the thicknesses of the first dielectric layer (51) and the third dielectric layer (53) in a lamination direction.
