This application claims benefit of priority to Korean Patent Application No. 10-2018-0083118 filed on Jul. 17, 2018 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to an antenna module.
Recently, in accordance with the trend for thinness of electronic devices, thicknesses of various components in a mobile device, such as a smartphone, are significantly limited. Therefore, when a millimeter wave/5G antenna module is used in a mobile device, inevitably there are many limitations in a size, a thickness, and the like, of the millimeter wave/5G antenna module antenna module in order to secure a degree of freedom of a mounting position of the millimeter wave/5G antenna module within a set.
An aspect of the present disclosure may provide an antenna module of which a degree of freedom may be secured when the antenna module is mounted in a set by a reduction in an overall thickness thereof.
According to an aspect of the present disclosure, an antenna module may be provided, in which a semiconductor package including a semiconductor chip is mounted on an antenna substrate and a passive component having a thickness greater than that of the semiconductor chip is mounted separately from the semiconductor package on the antenna substrate or a connection substrate.
