Abstract:
A flat antenna unit for a mobile communication equipment which is pasted on the mobile communication equipment so that it is touched by a human hand when in use, comprising:a flexible insulated base;a receiving circuit which is formed on the surface of said flexible insulated base and which comprises three conductive layers of a pair of U-shaped conductive layers which are isolated and symmetrically disposed each other, a pair of conductive layers which have bent sections at the ends thereof and which are isolated and symmetrically disposed on the both sides of said U-shaped conductive layers, and a conductive layer which is isolated from said conductive layers as well as from said U-shaped conductive layers and which is located above said U-shaped conductive layer; andan insulator coated on said receiving circuit;said flat antenna unit for a mobile communication equipment being characterized in that when a human hand touches said insulator, a tuning capacitor is formed between said hand and said receiving circuit via said insulator.
