An antenna apparatus used in a wireless communication medium or a wireless communication medium processing apparatus constructed by a constitution of including a magnetic member in which a magnetic ceramic powder is used as a major component thereof and which is provided with flexibility; an antenna formed at a surface or inside of the magnetic member, and a matching circuit of the antenna formed at the surface or the inside of the magnetic member.

Antenna apparatus

An antenna apparatus used in a wireless communication medium or a wireless communication medium processing apparatus constructed by a constitution of including a magnetic member in which a magnetic ceramic powder is used as a major component thereof and which is provided with flexibility, an antenna formed at a surface or inside of the magnetic member, and a matching circuit of the antenna formed at the surface or the inside of the magnetic member.

Antenna apparatus employing a ceramic member mounted on a flexible sheet

An electronic component has an element, a pair of terminal portions which are disposed on the element, and an external covering material which covers a part of the terminal portions and the element. The electronic component is configured such that inclined portions are disposed on corner portions of a bottom surface and side surfaces of the external covering material, and the terminal portions are protruded from corner portions where the inclined portions and the bottom surface of the external covering material intersect.

Electronic component

The invention is to provide such an antenna module making broadband of transmitting and receiving frequencies, while realizing miniaturization. The invention has a structure comprising a mounting body; a chip antenna having a substrate mounted on the mounting body and a substrate and a couple of terminal parts provided on the substrate; an feeding portion to which one of the terminal parts provided on the mounting body is connected; a open portion to which the other of the terminal parts provided on the mounting body is connected; and a capacitive conductor provided in opposition to the substrate, thereby to make use of a bottom area hidden when mounting the chip antenna so as to increase capacitive components for realizing broadband of the antenna module.

Antenna module

This invention is a wireless communication medium processing apparatus which carries out communication with a wireless communication medium, to carry out at least one of reading and writing as to information which was stored in the wireless communication medium, and has a plurality of antenna, a transmission divider which was connected to the plurality of antennas, and a reception compositor which was connected to the plurality of antennas, and is characterized in that the transmission divider divides an inputted signal to output the plurality of antennas, and the reception compositor combines signals from the plurality of antennas and outputs it.

Wireless communication medium processing apparatus and wireless communication medium processing system

A synchronous signal position detection unit detects symbol synchronous signals according to OFDM from the signals received by the respective antennas. A delay measurement unit measures a relative delay between the symbol synchronous signals for each antenna series and makes a notice to a memory unit via a delay amount notification unit. A diversity operation implementation unit temporally aligns the carrier data positions of the OFDM symbols for each antenna series so as to implement a space diversity operation.
