Compact antenna and producing method thereof |
摘要 |
A compact antenna comprises a core which is a hard linear member having a predetermined shape corresponding to resonance characteristic, a conductor film which covers at least a portion of an outer surface of the core and which has higher electric conductivity than that of the core, and a substrate which closely surrounds and holds the outer surface of the core covered with the connection film. A film thickness of the conductor film is equal to a skin depth and thus, it is possible to inexpensively maintain reliability, and to prevent radiation efficiency from being lowered.
