Abstract
The utility model discloses an omni-directional shaped micro-strip array antenna. The omni-directional shaped micro-strip array antenna includes eight branch antennas, an outer cylinder and two fixed plates. Back parts of the eight branch antennas form a cylinder body with an inner cavity of the shape of a regular octagon. Edges of the neighboring branch antennas are kept in a certain distance. The two fixed antennas are fixed on the upper end and the lower end of the cylinder body composed of the eight branch antennas. The branch antennas are fixed on the fixed plates respectively through screws, so that the eight branch antennas are integrated together. The outer cylinder is covered outside the cylinder body composed on the eight branch antennas. The omni-directional shaped micro-strip array antenna is composed of the eight branch antennas. Each of the branch antennas is a directional shaping antenna.
