Title:
ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2023/120075
Kind Code:
A1
Abstract:
An antenna module (1) is provided with: a first antenna device (100) having a resonance frequency (F1); a second antenna device (200) having a resonance frequency (F2); and, a pass filter (10) connected between a prescribed position of the second antenna device (200) and ground. The first antenna device (100) includes a radiation element (101) connected to a feed circuit (RF1). The second antenna device (200) includes a radiation element (201) connected to a feed circuit (RF2). The pass filter (10) blocks the resonance frequency (F2), and the radiation element (101) and the radiation element (201) are coupled by at least one of an electric field and a magnetic field, so that a resonance frequency (F3) of a parasitic antenna (300) for functioning in a path that passes through the radiation element (201) via the pass filter (10) from ground is passed.
