Abstract: A dual antenna device comprises a substrate, a first antenna, a second antenna and an isolation element. The substrate comprises an installation surface, the first antenna and the second antenna protrude from the installation surface and respectively couple to the installation surface by the first grounding edge and the second grounding edge. The isolation element comprises a first isolation portion protruding from the installation surface and coupling to the installation surface by a bottom side of the first isolation portion so that the first antenna and the second antenna respectively locate at both sides of the isolation element. The first antenna and the isolation element form a first interval in the extension direction of the first grounding edge. The second antenna and the isolation element form a second interval in the extension direction of the second grounding edge. The design of the isolation element improves the isolation magnitude.

Abstract: An antenna module mainly includes at least one antenna capable of radiating signals of two frequencies, a grounding portion, and at least one isolation metal sheet capable of isolating signals of a frequency generated by different antennas from each other to avoid interference. The antenna module is integrally formed, which can reduce the volume of the antenna module, and provide a stable radiation pattern and broadband and multi-band functions.
