The present invention relates to a protective member having a plate shape, including: a first base material that is a chemically strengthened glass, and a second base material provided in a hole recessed or penetrating in a thickness direction of the first base material and formed of a material different from a material forming the first base material, in which with respect to values of relative permittivity and dielectric loss tangent at a frequency of 10 GHz of the first base material and the second base material, the value of at least either one of the relative permittivity and the dielectric loss tangent of the second base material is smaller than the value of the relative permittivity or the dielectric loss tangent of the first base material.

An antenna device and an electronic device are provided. The antenna device includes an antenna radome and an antenna module. The antenna radome includes a dielectric substrate and a resonance structure carried on the dielectric substrate. The antenna module is spaced apart from the antenna radome and configured to perform at least one of receiving and transmitting a radio frequency signal of a preset frequency band in a radiation direction which is directed toward the dielectric substrate and the resonance structure. The resonance structure has an in-phase reflection characteristic for the radio frequency signal of the preset frequency band, and a distance between a radiation surface of the antenna module and a surface of the resonance structure facing the antenna module is determined by a reflection phase difference of the antenna radome and a wavelength of the radio frequency signal of the preset frequency band transmitted in air.

An electronic apparatus is provided. The electronic apparatus includes a rear cover, an antenna module spaced from a rear cover, a radiation array configured to radiate millimeter wave signals and at least one array structure arranged on a first area of the rear cover. A beam of the millimeter wave signals points out of the rear cover. Each of the at least one array structure includes periodically arranged array members. The first area at least includes an area projected by the antenna module on the rear cover. The millimeter wave signals are coupled with the at least one array structure and radiated out of the rear cover through the at least one array structure.

Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed.
