Antenna board assembly and antenna apparatus including same

An antenna board assembly comprising:

• a reflecting panel provided to forward reflect antenna beams radiated by multiple array antenna elements that are provided in front of the reflecting panel;
• a rear panel stacked and coupled to a rear surface of the reflecting panel and made of a non-conductive material;
• and
• a front panel stacked and coupled to a front surface of the reflecting panel and made of a non-conductive material,
• wherein the rear panel and the front panel are integrally molded by a dual injection method, and the rear panel and the front panel are stacked and coupled on the basis of the reflecting panel made of a metal material,
• wherein the antenna board assembly further comprises multiple feed strip lines coupled to the front surface and rear surface of the reflecting panel in order to supply power to the multiple array antenna elements, and
• wherein at least one connection hole is formed in the reflecting panel in forward and backward directions thereof in a way to penetrate the reflecting panel so that some of the multiple feed strip lines provided to supply power to the multiple array antenna elements are connected from the rear surface of the reflecting panel to the front surface thereof in a way to penetrate the reflecting panel.

An antenna apparatus comprising:

• an RF filter comprising multiple unit RF filter bodies stacked and disposed on a front surface of a main board;
• and
• a radiation element module comprising multiple array antenna elements provided to be electrically connected to a front of the RF filter and arranged to implement antenna beamforming,
• wherein the radiation element module comprises an antenna board assembly, comprising a reflecting panel provided to forward reflect antenna beams radiated by the multiple array antenna elements, a rear panel stacked and coupled to a rear surface of the reflecting panel and made of a non-conductive material, and a front panel stacked and coupled to a front surface of the reflecting panel, and
• the rear panel and the front panel are made of a plastic resin material and are integrally molded by a dual injection method, and the rear panel and the front panel are stacked and coupled on the basis of the reflecting panel made of a metal material.
