摘要： The present disclosure relates to the anti-reflection structure for millimeter wave application and the user's equipment comprising the same. The anti-reflection structure of the present disclosure includes the comprises at least one antireflection film with a specific thickness, permittivity (Dk), a permeability (Uk) of 1 to 2, and a dissipation factor (Df) of 0 to 0.1. According to the anti-reflection structure, it has advantageous transmittance and reflectance in a bandwidth with a frequency of 20-45 GHz

摘要： The invention provides a near field communication module comprising: a magnetic substrate having opposing first and second surfaces and first and second through holes extending from the first surface to the second surface; and an antenna comprising: an annular coil having first and second ends, first and second feeding points, and first and second connecting lines for connecting the first and second ends of the annular coil to the first and second feeding points, respectively, wherein the antenna is configured such that the annular coil is provided on the first surface of the magnetic substrate, the first and second feeding points are provided on the second surface of the magnetic substrate, and the first and second connecting lines extend through the first and second through holes, respectively. The near field communication module has a greatly simplified structure and markedly reduced total thickness and significantly improved mechanical properties, such as rigidity.
