Title:
ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2019/167403
Kind Code:
A1
Abstract:
The present invention suppresses deviation of the characteristics of an antenna module from the desired characteristics. An antenna module (100) according to one embodiment of the present invention is provided with a dielectric substrate (130), a first antenna element (1111), a first high frequency element (190) and a first heat dissipation member (120). The first antenna element (1111) is formed on the dielectric substrate (130). The first high frequency element (190) supplies electric power to the first antenna element (1111). The first heat dissipation member (120) conducts the heat of the first high frequency element (190) to the outside. The dielectric substrate (130), the first high frequency element (190) and the first heat dissipation member (120) are sequentially stacked in this order in the Z-axis direction, which is the normal direction of the dielectric substrate (130). The first heat dissipation member (120) contains a metal. A first width (W11) at a first position (P11) is different from a second width (W12) at a second position (P12) that is at a distance from the first position (P11) in the Z-axis direction.
