11. A multiband antenna, comprising:
-
a first radio unit, the first radio unit being a planar sheet and a rectangular frame, the working frequency bandwidth of the multiband antenna being regulated by changing the lengths of the sides of the first radio unit; and a second radio unit, the second radio unit being a planar sheet and including a main portion and a plurality of arm portions connected to the main portion;
wherein the arm portions cooperate with the main portion to form a plurality of sub-radio units, and the sub-radio units are coupled with each other to regulate the working frequency bandwidth of the multiband antenna. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
