Summary:PROBLEM TO BE SOLVED: To provide a planar antenna which resonates with a simple structure and is commonly usable for two or three frequencies at low cost and superior in general purpose availability. SOLUTION: A flat ground conductor 2 is bonded adjacently to a tabular dielectric substrate 1, and a feed point 3 is provided on the boundary between the ground conductor 2 and the dielectric substrate 1. A main element 4 is laid from the feed point 3 on the substrate 1, and a sub-element 5 is branched from a mid position of the main element 4 and laid on the substrate 1. COPYRIGHT: (C)2004,JPO
