Abstract
The present invention relates to an antenna device and, particularly, the antenna device comprises: a printed board assembly (hereinafter, referred to as 'PBA') having a plurality of antenna-related components mounted on one surface thereof, and having a plurality of filters mounted on the other surface thereof, an antenna board which is arranged to be stacked on one surface side of the PBA, and which has a plurality of antenna elements mounted on one surface thereof and connected to construct electrical signal lines with the filters in close contact with the other surface thereof, and clamshell units interposed between the other surface of the PBA and one surface of the filters to perform a signal shielding function, wherein the insides of the clamshell units include strip line connectors which absorb the assembly tolerance between the clamshell units while being partially deformed by means of the adhesion of the filters during close-coupling of the filters, and which shield a signal by means of ground surfaces arranged around the strip line connector while constructing the electrical signal lines, and thus the manufacturing cost of the filters is reduced and impedance properties are prevented from being easily disrupted.
