摘要： A method accurately inspects whether an IC inlet to be inspected is non-defective or defective in a state in which a large number of IC inlets are formed over an insulating film. The inspection of IC inlets formed over an insulating film is performed by transmitting microwaves to the IC inlets from antennas. To selectively irradiate the microwaves to only one IC inlet to be inspected out of a large number of IC inlets that are formed over the insulating film, a radio-wave absorbing plate is inserted between the insulating film and the antennas, and the microwaves are irradiated to the IC inlet through a slit formed in the radio-wave absorbing plate. The radio-wave absorbing plate is configured such that the slit, which is substantially equal to the IC inlet in size, is formed in a portion of a planar plate that is formed of a radio-wave absorber.

摘要： The present invention relates to a structure of an antenna and its shielding structure for a mobile phone which may significantly reduce the hazardous electromagnetic wave transmitted to the user's body. The present invention arranges a monopole antenna inside of the mobile phone housing, and installs an electromagnetic wave absorber between the antenna and the circuit board. The electromagnetic wave absorber can absorb the electromagnetic wave reflected form conductive plate constituting the circuit board. Thus, the adverse effect of the reflected electromagnetic wave to the performance of antenna is prevented and the amount of the electromagnetic wave to which the users is exposed can be significantly reduced as well.

摘要： A wireless communications device with low magnetic field emission is provided by disposing a magnetically absorptive material near the base of an antenna of a handset of the device. The magnetically absorptive material is preferably a ferrite-type metal oxide dispersed within a silicone rubber medium. The ferrite-type metal oxide acts to attenuate the magnetic field generated in the near field of the antenna. Interference with hearing aids worn by wireless communications device users is thereby reduced.
