In order to solve a problem that, if a reinforcing plate of a housing is used as an antenna in a receiver, a desired antenna gain is less likely to be obtained and therefore an antenna gain is degraded, a receiver for receiving information transmitted by a radio wave includes an output portion configured to output information which is receivable by a viewer or another receiver; a stand portion contacting the output portion and configured to hold the output portion on an installation surface at an angle suitable for receiving the information or viewing an image; a reinforcing portion contacting the output portion and the stand portion at points other than a contact point between the output portion and the stand portion and configured to reinforce the output portion and the stand portion so that the angle is maintained; and an antenna portion arranged in a space ensured by at least the reinforcing portion and configured to receive the radio wave.

Receiver

A small antenna system which is incorporated in a portable radio apparatus and can ensure high antenna performance in a wide frequency band without impairing the design property or the operability and a portable radio apparatus are provided. An antenna device includes an antenna Ahaving a resonance characteristic in a first frequency; an antenna Ahaving a resonance characteristic in a second frequency and being spaced from the antenna Aat a predetermined distance; a circuit board P provided in a mobile telephone, a wireless sectionprovided on the circuit board P for supplying or receiving high-frequency power; and a high-frequency switchprovided on the circuit board P for selecting connection of an output terminal or an input terminal of the wireless sectionand a feeding point of the antenna Aor the antenna Aso that the feeding point of the antenna Aor the antenna Acan be switched and connecting to the wireless section

Antenna device and portable radio apparatus

An antenna unit and a communication apparatus are provided, which are operable with respect to wireless systems having three, or more frequencies by employing 2 sets of antenna elements, and which can realize such an antenna structure having a high freedom degree, while the antenna structure can be applied to frequency arrangements as to the plurality of wireless systems. An antenna unit includes a first antenna elementconnected to a first wireless system operated in a first frequency band, to which electric power is fed; and a second antenna elementconnected to a second wireless system operated in a second frequency band and a third frequency band, to which electric power is fed; in which the first antenna elementand the second antenna elementare arranged in a predetermined interval in a substantially parallel manner; and a cut off sectionfor electrically cutting off a connection between the first antenna elementand the first wireless system is provided at a power feeding portion 'Pof the first antenna element

Antenna unit and communication apparatus

It is an object of the invention to provide a portable wireless apparatus capable of maintaining high quality of a communication in various using configurations obtained by a two-axis hinge mechanism. A portable wireless apparatus () having a two-axis hinge portion includes a first antenna () which is suitable for a talking state and a second antenna () which is suitable for a waiting state. The first antenna () or the second antenna () is selected based on a result of opening/closing detection decided from an angle &#x3b1; of a first axis () and the result of opening/closing detection decided from an angle &#x3b2; of a second axis (). Consequently, it is possible to select either of the antennas which is not influenced by hands or fingers of a user.

Portable wireless apparatus

To provide a cell phone equipped with a broadcast receiver that delivers a high receiving sensitivity and antenna performance in various usage states. A loop elementas an antenna for receiving television broadcast is arranged in a range (c) of an upper end portion of an upper housing. An end part of an upper circuit boardis matched with a portion shown by (a) so that a conductor other than the antenna element does not exist in the range (c). A monopole elementfor cell phone communication is arranged at a lower end portion of a lower housing

Portable telephone with broadcast receiver

The objective of the present invention is to provide a connection cable that serves as an external antenna for a radio apparatus, and whose antenna performance is not deteriorated in the use state by an adverse affect attributable to the near proximity of a human body. According to the present invention, an antenna device, integrally formed with first connection means, which is to be connected to a radio apparatus, second connection means, which is to be connected to a peripheral device, and a connection cable and an antenna element, which are located in between and which transmit a plurality of signals from the radio apparatus to the peripheral device, includes: first relay means, located at a middle position in the connection cable, for relaying the plurality of signals; the antenna element, located between the second connection means and the first relay means; and a coaxial line, located between the first connection means and the first relay means for transmitting, to the radio apparatus, an antenna reception signal that has been received at the antenna element and has been extracted by the first relay means, wherein the antenna element serves as an external antenna for the radio apparatus.

Antenna device with integrated connection cable, and radio apparatus

A conductive metal frame attached to an upper case is electrically connected to hinge metal member. The hinge metal member is connected to a hinge metal member by a rotary shaft in a rotatable manner. The hinge metal member, a further hinge metal member, and the rotary shaft are made of conductive metal so that electric continuity is obtained at contact points thereamong. The further hinge metal member is connected to a matching circuit on a circuit board via a feedpoint terminal. A conductor element is connected to a ground pattern of the circuit board at a position close to a point at which the matching circuit is grounded. The structure as described above provides a folding portable wireless unit that can secure a high antenna performance in a calling state and a waiting state.
