Title:
ANTENNA MODULE AND COMMUNICATION DEVICE ON WHICH ANTENNA MODULE IS MOUNTED, DIELECTRIC SUBSTRATE, AND MANUFACTURING METHOD OF ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2023/074306
Kind Code:
A1
Abstract:
This antenna module (100) is provided with a dielectric substrate (105) and a radiation element (121A) arranged on the dielectric substrate (105). The dielectric substrate (105) includes flat parts (130A, 130B) which have mutual different normal directions, and a curved part (135) which connects the flat part (130A) and the flat part (130B). The curved part (135) includes a curved region (RG2) having a curvature. The flat part includes a straight region (RG1) with no curvature. The radiation element (121A) is arranged on the flat part (130A). In the Raman spectrum obtained with Raman scattering spectroscopic analysis of a cross section of the dielectric substrate (105), the wavenumber difference, which indicates the difference between the highest-frequency wavenumber in the straight region and the highest-frequency wavenumber in the curved region is at least 0.1 cm-1.
