Disclosed is a tri-band antenna with spiral parasitic patches. The tri-band antenna comprises: a primary radiator antenna where the spiral parasitic patch is attached to the upper portion on one side of a bar-shaped FR4 substrate, and a secondary radiator antenna where the spiral parasitic patch is attached to the upper portion on one side of the bar-shaped FR4 substrate. The secondary radiator antenna is distanced from the primary radiator antenna. |
