Patent abstract
In an antenna device, a half wavelength dipole antenna is folded so as to form a forward path section, a folding section and a backward path section such that the backward path section is connected to the substrate at the ground terminal, and an electric power is supplied from the power supply source at the branching point, so as to configure a folded monopole antenna. Also, an additional antenna is folded similarly and connected to the monopole antenna such that the branching point and the power supply section are shared by the monopole antenna and the additional antenna.
