Title:
ANTENNA MODULE AND WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/021807
Kind Code:
A1
Abstract:
In an antenna module (50), a first antenna unit (20) is connected to a power supply point (21) of a first conductive unit 1 and is connected electrically to a second conductive unit (2) through the first conductive unit (1) and a relay unit (12). The positional relationship between the power supply point (21) and the relay unit (12) is set such that, in a first virtual plane, the respective degrees of directivity of a horizontal polarized wave (Eθ) and a vertical polarized wave (Eφ) with respect to a set of angled diversity antennas (202a) is decreased compared to a case in which the first antenna unit (20) is directly connected to the second conductive unit (2).
