Document Type and Number:
WIPO Patent Application WO/2023/188785
Kind Code:
A1
Abstract:
An antenna module (100) comprises: a dielectric substrate (130); a grounding electrode (GND) disposed on the dielectric substrate (130); flat plate-shaped radiating elements (121, 122); and a peripheral electrode (150). The radiating element (121) is disposed opposite the grounding electrode (GND). The radiating element (122) is disposed between the radiating element (121) and the grounding electrode (GND). The peripheral electrode (150) is disposed in a layer between the grounding electrode (GND) and the radiating element (122) of the dielectric substrate (130), and is electrically connected to the grounding electrode (GND). The radiating element (122) emits radio waves in a frequency band lower than that of the radiating element (121). The peripheral electrode (150) includes a plurality of plate electrodes (151-156) stacked in a first direction, which is a direction in which the radiating element (121) and the grounding electrode (GND) oppose each other. The plate electrode (156) is disposed in a layer between the plate electrode (151) and the grounding electrode (GND). The size of the plate electrode (156) is smaller than the size of the plate electrode (151).
