Title:
ANTENNA MODULE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/167436
Kind Code:
A1
Abstract:
The present invention prevents directionality of radio waves radiated by an antenna module from deviating from a desired directionality due to temperature variations among a plurality of high-frequency elements. A first antenna element (1111) and a second antenna element (1121) are formed in a first dielectric substrate (131). The first antenna element (1111) is supplied with electric power from a first high-frequency element (191). The second antenna element (1121) is supplied with electric power from a second-high frequency element (192). The first dielectric substrate (131), the first and second high-frequency elements (191, 192), and a first heat dissipating member (120) are laminated in this order in the z-axis direction, which is a normal direction of the first dielectric substrate (131). When seen in a plan view from the z-axis direction, the first heat dissipating member (120) overlaps at least a portion of the first high-frequency element (191) and at least a portion of the second-high frequency element (192).
