Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal device such as a mobile phone, a mobile information processing device, a wireless LAN component device, a position information guide device such as a GPS, and the like. The present invention relates to a device with a wireless communication function provided with a communication circuit for performing communication using electromagnetic waves. 2. Description of the Related Art Generally, a device that performs wireless communication using electromagnetic waves transmits and receives a signal by attaching a resonant antenna to the outside. However, some mobile phones and other mobile devices
Some have an external antenna that can be accommodated and a reception-only internal antenna for standby, and others have only an internal antenna for short-range communication. These internal antennas may be metal plates (such as inverted F-type antennas for mobile phones) placed several millimeters away from high-frequency circuit boards, or dielectric ceramic blocks with electrodes (such as patch antennas). Yes, it is used by soldering on a substrate. FIG. 11 shows an example of a conventional mobile phone.
An internal antenna 54 is attached to a circuit board 52 provided therein. The internal antenna 54 is an inverted F-shaped antenna, and is disposed near the end of the housing 53 opposite to the battery housing 55. The casing 53 is provided with a shield plating layer (not shown) except for the vicinity of the antenna 54 which becomes an electromagnetic wave radiation part. [0003] In the case where an internal antenna is provided as shown in each of the above-mentioned conventional examples, it is necessary to secure a space for arranging the antenna in a housing space and on a circuit board. It was difficult to reduce the size and weight of devices with communication functions. Further, since miniaturization is difficult, the degree of freedom in external design has been limited in achieving miniaturization. An object of the present invention is to provide a device with a wireless communication function that can reduce the size and weight of the device and increase the degree of freedom in external design. [0005] A device with a wireless communication function according to the present invention is a device with a wireless communication function provided with a communication circuit for performing communication using electromagnetic waves. It is composed of an antenna. As the antenna, for example, a patch antenna can be used. According to this configuration, since a part of the housing becomes an antenna, a space for accommodating the antenna in the housing becomes unnecessary, and the size of the device can be reduced accordingly. The size of the device can be reduced, and the material of the housing is reduced only in the portion serving as the antenna, so that the weight is reduced. In addition, since there is no need for a space for accommodating an antenna therein, and the size of the device is easily reduced, the degree of freedom in external design is increased. The device with a wireless communication function according to the present invention can be generally applied to a device having a communication circuit that performs communication by electromagnetic waves, and includes a communication device such as a mobile phone dedicated to communication or having communication as a main function, a mobile information processing device For example, the main function of the device is different from communication, and the present invention can be applied to a device having a communication function. As the antenna, a dielectric resin antenna having a radiation electrode and a dielectric resin can be used. The dielectric resin antenna may be one in which a dielectric resin is interposed between the radiation electrode and the ground electrode, or one in which the ground electrode is omitted. The electrode such as the radiation electrode may be a metal conductor such as a metal foil or a conductive resin. As the dielectric resin antenna, a compact and high-performance one using a dielectric resin having a high dielectric property has been developed, and has an advantage of being superior in moldability as compared with a conventional ceramic dielectric. By using a resin having such high dielectric properties, it is possible to fit within the thickness of the housing. When the antenna is a dielectric resin antenna, it is preferable that portions of the housing other than the dielectric resin antenna are made of resin. If it is made of resin like this,
The integration of the dielectric resin antenna and other parts of the housing is easy. The integration can be performed as follows. For example, it is assumed that a portion other than the dielectric resin antenna of the housing is made of resin, and a portion other than the dielectric resin antenna and the dielectric resin antenna are integrally formed. Injection molding or the like is used for this integral formation. When the electrode serving as the radiation electrode or the like of the dielectric resin antenna is a metal material, this electrode is integrated with the housing by insert molding. In addition, the resin material serving as the dielectric of the dielectric resin antenna and the resin material forming the other parts of the housing can be injection-molded in the same mold by a two-color or three-color molding technique.
As described above, by adopting the method of injection-molding a plurality of kinds of resins in the same mold, a housing with a dielectric resin antenna can be manufactured with high productivity. Further, the dielectric resin of the dielectric resin antenna may be a coating layer of a resin material. For example, a part other than the dielectric resin antenna of the housing is injection-molded,
A discharge electrode is disposed on the case, or a housing including the radiation electrode is injection-molded, and thereafter, a dielectric resin of a dielectric resin antenna is applied. When the ground electrode is provided, the ground electrode is mounted on the applied dielectric resin. As described above, when the dielectric resin of the dielectric resin antenna is used as the coating layer, the number of coating steps is increased compared with the case where the whole is integrally formed by injection molding, but the injection molding technique is simplified and the manufacturing is facilitated. can do. In the device with a wireless communication function according to the present invention, the surface and outer periphery of the dielectric resin antenna on the outer surface of the housing are made of a resin having a lower dielectric constant than the dielectric of the dielectric resin antenna. The cover and other parts of the housing may be made conductive. Thus, by covering the surface of the dielectric resin antenna on the outer surface side of the housing with the low dielectric constant resin, the dielectric resin antenna can be protected from the outside of the housing while permitting passage of electromagnetic waves. In addition, by making the other part of the housing conductive, that is, by making the housing part other than the electromagnetic wave radiating part conductive, unnecessary parts from the high-frequency circuit board disposed in the housing are eliminated. In addition to blocking radiation, it is possible to block the entry of electromagnetic waves from outside. In addition, since the periphery of the dielectric resin antenna is covered with the low dielectric constant resin, interference between the conductive housing portion and the radiation electrode of the dielectric resin antenna can be avoided. [0010] The housing and the other parts may be made of a conductive resin, or may be made of a non-conductive resin to form a conductive coating to make the housing conductive. In the case of using a conductive resin, the step of forming a coating is not required, and the manufacturing process of the housing is simplified. [0011] The dielectric resin antenna may be provided on a housing component with an antenna separate from the main body of the housing and attached to the main body of the housing. The antenna-equipped housing component has a dielectric resin antenna having a radiation electrode and a dielectric resin, and a low-permittivity resin portion covering a surface and an outer periphery of the dielectric resin antenna on the outer surface of the housing, This low dielectric constant resin portion may be made of a dielectric resin having a lower dielectric constant than the dielectric of the dielectric resin antenna. As described above, when a housing component with an antenna that is separate from the main body of the housing is used, the housing component with the antenna can be mass-produced as a common component for various housings, and manufacturing of the housing can be performed. Can be simplified, and it is easy to respond to design changes and the like. FIG. 1 shows a first embodiment of the present invention.
And FIG. The device 1 with a wireless communication function is a device with a wireless communication function provided with a communication circuit 2 for performing communication using electromagnetic waves, and a part of a housing 3 is configured with an antenna 4 for the communication. Therefore, the housing 3 is a housing with an antenna. The device 1 with a wireless communication function may be a device provided with a communication circuit 2 for performing communication using electromagnetic waves, but this embodiment shows an example applied to a mobile phone. The communication circuit 2 includes a housing 3
It is provided on a circuit board 5 housed therein, and is connected to the antenna 4 by wiring or a connector (not shown) or the like. The housing 3 is composed of a plurality of divided housings 3A and 3B, and a part of the divided housing 3A is the antenna 4. The antenna 4 is a dielectric resin antenna having a radiation electrode 6 and a dielectric resin 8 as shown in an enlarged view in FIG. 1B, and includes a radiation electrode 6 and a ground electrode 7. The patch antenna has a dielectric resin 9 interposed therebetween. The dielectric resin 9 of the dielectric resin antenna 4 is a high dielectric constant resin. The radiation electrode 6 and the grounding electrode 7 are made of a metal conductor such as a metal foil or a conductive resin. A surface and an outer periphery of the dielectric resin antenna 4 on the outer surface side of the housing 3 are covered with a low dielectric resin 9 having a lower dielectric constant than the dielectric resin 8 of the dielectric resin antenna 4.
The portion of the low dielectric constant resin 9 includes an outer surface covering portion 9a that covers the outer surface side of the dielectric resin antenna 4 and an outer peripheral portion 9b that surrounds the outer periphery. The other part of the housing 3, that is, the general part 3a is made of conductive resin and is conductive. The dielectric resin 8 of the dielectric resin antenna 4, the low dielectric constant resin 9 of the housing 3, and the resin material of the general portion 3a are all resin materials that can be injection-formed, and are, for example, thermoplastic resins. In the dielectric resin antenna 4, the ground electrode 7 may be omitted. In this case, as shown in FIG.
The dielectric resin antenna 4 includes a radiation electrode 6 and a dielectric resin 9. Further, the portion of the low dielectric constant resin 9 of the dielectric resin antenna 4 may be an insulator. The general portion 3a of the housing 3 is made of a non-conductive resin instead of using a conductive resin, and is provided with a conductive coating 11 as shown in FIG. 6, so that the general portion 3a has conductivity. Is also good. The coating 11 can use, for example, shield plating. As a method of manufacturing the casing 3, for example, the following 2
Different methods can be adopted. (1) A method of injection molding the whole. By insert-molding the electrodes 6 and 7 of the dielectric resin antenna 4, the entire casing 3 (or the divided casing 3A) is integrally injection-molded. When the housing 3 is composed of a plurality of split housings 3A and 3B as in this embodiment, the entire split housing 3A having the dielectric resin antenna 4 of the housing 3 is integrally injection-molded. When injection molding is performed integrally as described above, the dielectric resin 8 of the dielectric resin antenna 4, the low dielectric constant resin 9 of the housing 3, and the resin material of the general portion 3a are:
Because each material is different, by three-color molding method,
These resin materials are integrally molded in the same mold.
When the entire casings 3 and 3A are injection-molded as described above, productivity is improved. When the electrodes 6 and 7 of the dielectric resin antenna 4 are made of a conductive resin, the entire casing 3 and 3A including the electrodes 6 and 7 are formed in the same mold by a multicolor molding technique without using insert molding. Injection molding may be performed integrally. (2) A method using coating. As shown in FIG. 3A, the general portion 3a of the housing 3 and the portion of the low dielectric constant resin 9 are injection molded integrally, and the low dielectric constant resin 9 is formed.
The radiation electrode 6 is attached to the inside (FIG. (B)), and a dielectric resin 8 is applied to the inside (FIG. (C)). further,
The grounding electrode 7 is attached inside (FIG. 3D). The attachment of the radiation electrode 6 may be performed by bonding or by forming a coating layer to be the radiation electrode 6 by vapor deposition. At the time of injection molding with a part, insert molding may be performed. The attachment of the ground electrode 7 may be performed by adhesion or vapor deposition. When the portion of the dielectric resin 8 of the dielectric resin antenna 4 is formed by coating as described above, the general portion 3a of the housing 3 and the portion of the low dielectric constant resin 9 can be integrally injection-molded by two-color molding. It can be manufactured at low cost with a simple molding technique. For connection of the wiring to the radiation electrode 6 in the dielectric resin antenna 4, for example, a through hole (not shown) is provided in the dielectric resin antenna 4 and connected to this through a wiring (not shown). In addition, as shown in FIG. 4, a terminal 10 connected to the radiation electrode 6 may be provided so as to be exposed on the inner side surface of the housing of the dielectric resin antenna 4, whereby the connection of the wiring is reduced. Easy to do. The above-described configurations described with this embodiment can be applied not only to the case where the device 1 with a wireless communication function is a mobile phone but also to a general device with a wireless communication function having a communication circuit 2 for performing communication using electromagnetic waves. . When the device 1 with a wireless communication function is a mobile phone, the housing 3 is composed of a plurality of, for example, two divided housings 3A and 3B as described above, and the two divided housings 3A and 3B are joined together at the peripheral edge to form an interior. The space is a hollow housing 3 in a closed state. Among them, the dielectric resin antenna 4 is provided in the divided housing 3A on the back side of the device. A battery storage space 12 is formed in the rear divided housing 3A,
The battery storage space 12 is closed by the open / close lid 3C. As shown in FIG. 2, the divided housing 3B on the front side is provided with a screen display unit 13 and a plurality of operation units 14 including key switches and the like. An example of the material of each resin will be described. The dielectric resin 8 of the dielectric resin antenna 4 is not particularly limited as long as a predetermined dielectric portion can be formed. However, a resin having excellent heat resistance and strength is preferable. Thermoplastic aromatic polyester resin, polyphenylene sulfide resin, syndiotactic polystyrene resin, polyphenylene ether resin, polyetherimide resin,
Thermoplastic resins such as polycarbonate resin, polyacetal resin, polysulfone resin, polyethersulfone resin, polyamide imide resin, polyarylate resin, 5-methylpentene resin, polyethylene terephthalate resin, polyarylene sulfide resin, epoxy resin, and phenol resin And thermosetting resins such as unsaturated polyester resins and polyetheretherketone resins. These may be two or more alloys. The dielectric resin 8 may be blended with one or more of the above-listed resins, if necessary, of a fibrous or particulate dielectric ceramic having a small dielectric tangent to achieve a desired dielectric constant. The adjusted resin composition may be used. Such dielectric ceramics include, for example, barium titanate, strontium titanate, calcium titanate,
Barium strontium titanate, composite of amorphous titanium oxide and alkaline earth metal titanate, calcium zirconate such as lead zirconate titanate, wollastonite, zonotrite, magnesium borate, aluminum borate, zinc silicate, etc. Fibrous material and particulate material. Specific examples of the resin composition include, for example,
A plastic resin in which barium titanate is blended with a thermoplastic resin can be used. As the thermoplastic resin, a resin whose main component is a polyarylene sulfide resin can be employed. The low dielectric constant resin 9 has a low dielectric constant,
A material having a small Tan δ is preferable. What is Tan δ?
The dielectric loss tangent means that the smaller this value is, the smaller the loss of the electromagnetic wave transmitted through the material is (the smaller the Tan δ is, the more suitable the member covering the antenna). As the low dielectric resin 9, for example, PTFE (polytetrafluoroethylene), FEP (fluoroethylene propylene), PE (polyethylene), PP (polypropylene), PPE (polyphenylene ether), SPS (syndiotactic polystyrene), or the like is employed. it can.
In the above, all have a dielectric constant of 2 to 3 and a Tan δ of 0.0
01 or less, which is a relatively low value among resins. The conductive resin used for the general portion 3a of the housing 3 is obtained by dispersing a conductive material in the resin. Metals such as gold, silver, aluminum, aluminum and palladium are used as the conductive substance. These metals are dispersed in PVC, acrylic resin, silicone rubber or the like.
Further, carbon black, graphite, carbon fiber and the like may be dispersed in a thermoplastic resin. According to the device 1 with the wireless communication function having this configuration, since a part of the housing 3 becomes the antenna 4, a space for accommodating the antenna in the housing 3 becomes unnecessary, and the device can be downsized accordingly. The size of the device can be reduced, and the material of the housing 3 can be reduced only in the portion that becomes the antenna 4, so that the weight can be reduced. Further, since there is no need for a space for accommodating an antenna therein, and the size of the device is easily reduced, the degree of freedom in external design is increased. Although the antenna 4 is a dielectric resin antenna 4,
As the dielectric resin antenna, a small and high-performance dielectric resin using a dielectric resin having a high dielectric property has been developed. By using a resin having such a high dielectric property, the general portion 3a of the housing 3 can be formed. It is possible to fit within the same thickness. Since the size of the device is reduced in this way, it is possible to reduce the price. In the above embodiment, the dielectric resin antenna 4 is integrated as a part of the housing 3 from the production process. For example, as shown in FIG. It may be provided as a housing component 20 with an antenna separate from the main body of the housing 3 and attached to the main body of the housing 3. This attachment may be made integral by melting the resins, or may be made by bonding or fitting. In the example shown in the figure, the dielectric resin antenna 4 of the first embodiment (FIG. 1) and the low dielectric constant resin 9 covering the outer surface and outer periphery of the housing constitute the housing component 20 with the antenna. Have been. The main body of the housing 3 includes the general portion 3a, and has a mounting hole 21 for the dielectric resin antenna 4 formed therein. The housing component 20 with the antenna is fitted into the mounting hole 21, and the general portion 3 as the housing body is bonded or bonded by heating and melting.
a. The main body of the housing 3 has a configuration in which the mounting hole 21 is opened,
0 may be insert-molded as an insert. The housing component 20 with an antenna may be detachable as an opening / closing lid of the housing 3. FIG. 8 shows a modification of the housing component parts with an antenna. Housing component 20A with antenna of this example
Is composed of the housing component 20 with the antenna of the example of FIG. 7 and the conductive resin portion 22 on the outer periphery of the low dielectric constant resin 9. The antenna-equipped housing component 20A is fitted in a mounting hole 21A formed in the general portion 3a serving as the main body of the housing 3 so as to be detachably attached. In the case of this configuration, the antenna-equipped housing component 20 </ b> A can also serve as an open / close lid for opening the inside of the housing 3. In each of the above embodiments, the case where the housing 3 is the housing of the device with the wireless communication function itself and accommodates the communication circuit 2 has been described. As shown in FIG. 9, a device 1 with a wireless communication function is composed of a communication device 30 having an independent housing 31 and a housing 32 that is an outer shell of the device 1 with a wireless communication function in which the communication device 30 is mounted in a built-in state or the like.
