Title:
ANTENNA MODULE AND COMMUNICATION DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2023/037805
Kind Code:
A1
Abstract:
An antenna module (100) comprises: dielectric substrates (130A, 130B) having differing normal directions; radiating elements (121A, 122A) and a ground electrode (GND) disposed on the dielectric substrate (130A); and radiating elements (121B, 122B) disposed on the dielectric substrate (130B). The radiating element (121A) can emit radio waves of a first frequency band. A radiating element (122) is disposed adjacent to the radiating element (122A) and can emit radio waves of a second frequency band higher than the first frequency band. The radiating element (121A) is disposed on the dielectric substrate (130A) at a position closer to the dielectric substrate (130B) than the radiating element (122A). The distance from the center of the radiating element (121A) to an end surface, of the ground electrode, near the dielectric substrate (130B) is shorter than the distance from the center of the radiating element (121A) to an end surface, of the ground electrode, far from the dielectric substrate (130B).
