Abstract
A multi-antenna structure with high-isolation effect includes a substrate and a plurality of antennas. The substrate, formed as a symmetric polygonal metal board, has a plurality of grooves and a plurality of board edges. The antennas vertically installed on the board edges and having a conjunction portion close to the substrate includes a support member and a feed-in member. A radiation member of the antenna connected perpendicular to the support member and the feed-in member has a free radiation end. If virtual extension lines from the radiation ends of any two neighboring antennas are crossed, at least two grooves are constructed in between thereof. If virtual extension lines of the radiation ends of any two neighboring antennas don't cross, at least one groove is constructed between the two neighboring antennas. The groove is applied to avoid signal interference between any two neighboring antennas.
