Definitions

  • the present invention relates to an intenna, more specifically to an intenna which can improve productivity because it is not the one assembled by separately fabricating the metal portion of the intenna but the one in which rod wires are bent in a desired shape and attached to the surface of synthetic resin material.
  • the intenna which is an embedded antenna as shown in Fig. 1, refers to a device slimmed to reduce the whole volume of the radio equipment unlike the external antenna that is mounted on the outside of radio equipment.
  • the intenna is a folded monopole intenna for sending and receiving a radio signal by supplementing a folded monopole antenna mounted on a wireless application.
  • Such intenna is known to drastically improve the quality of sending and receiving a radio signal by decreasing the impedance to a specific resistance level of metal by realizing an intenna pattern consisting of a feeding point structure proceeding upward so as to form an inductance of a value L and an offset point structure located in parallel at a position adjacent to the feeding point structure to form a capacitance of a value C.
  • FIG. 2 is a perspective view showing a conventional intenna.
  • the conventional intenna is assembled manually to fix a metal part 20 to the surface of the base 10 of synthetic resin material, so it has disadvantages that it needs many processes, has low productivity and high prices.
  • the present invention is to solve the conventional problems as mentioned above with a main object to provide an intenna in which the base of intenna is made of synthetic resin material, and a plurality of bosses that repeat continuously at a given gap are formed on the surface of each part, and rod wires are bent to be fusion- fixed between these bosses so that they can be fabricated very easily, while greatly contributing to shortening of the production process and reduction of the production cost.
  • an intenna comprising a base formed by the injection molding of synthetic resin material, wherein a plurality of bosses are formed continuously and repetitively at a given gap on each surface of the base; and rod wire which is bent in a given shape along the gap between said bosses and one end of which is connected to a tangential terminal provided on one side of said base.
  • the bosses are formed on the front surface, left and right side surfaces, as well as upper surface and lower surface of the base, and a part of the rod wire can be inserted between said bosses.
  • the gap between the bosses is of the same dimension as the thickness of the rod wire so as to prevent the rod wire inserted between the gap from moving freely.
  • the rod wires are prevented from breaking away by means of heat fusion of the front end portion of some bosses, after the rod wires are inserted in the gap between the bosses.
  • the base has a pair of plane portions bent at a predetermined angle of in the mutual contacting portion and maintained in a shape of so as to prevent reflection of radio waves and make absorption of them easy and the bosses are formed on the pair of plane portions.
  • the plane portions have turned-down portions at both ends thereof and coupling protuberances for assembly to the printed circuit board are formed in each turned-down portion.
  • the turned-down portion is formed at one end of the plane portions by extending therefrom.
  • the pair of plane portions are provided with plane-shaped connecting portions in the mutual contacting portions.
  • intennas very simply and easily by making the base of intenna with synthetic resin material, forming a plurality of bosses that repeat continuously at a given gap on the surface of the intenna, and configuring rod wire between these bosses in such a way that rod wire is bent and fixed together in fusion. It is also possible to greatly contribute to reduction of the production cost through automation of the production process.
  • V shape is provided with V-shaped planes, it prevents reflection of radio waves.

  • FIG. 3 is a perspective view showing an intenna of the present invention.
  • FIG. 4 is a sectional view showing the structure of the intenna of the present invention
  • Fig. 5 is a perspective view showing an intenna according to another embodiment of the present invention

  • the intenna of the prevent invention comprises a base
  • each surface of the base 30 are formed a plurality of bosses, that repeat continuously at a given gap G, by the injection molding method of synthetic resin material, as shown in Fig. 3.
  • the gap G between bosses is determined by the thickness of rod wire 40, and by using these bosses, rod wire 40 can be bent to be laid out at a large width on the front surface 32, left and right side surfaces 33, as well as upper surface 34 and lower surface 35 of the base 30.
  • the rod wire 40 is preferably copper wire, but any other metal rod wires that are suitable for antenna can be used.
  • This kind of work process can be easily automated by the method of bending and inserting rod wire, using, for example, robotic arm with the base 30 fixed on jig. Also, it is preferable to prevent rod wires from breaking away by heat fusion of the end portion of some of bosses, after inserting rod wires 40 in the gap G between bosses 31 according to the embodiment.
  • FIGs. 5 to 7 show intennas according to another embodiment of the present invention.
  • a base 30a has a pair of plane portions 36 bent at a predetermined angle of in the mutual contacting portion and maintained in a shape of V so as to prevent reflection of radio waves and make absorption of them easy.
  • bosses 31 which are the same as in the aforementioned embodiment are formed on the pair of plane portions 36 to make up the intenna.
  • the plane portions 36 have turned-down portions 37 at the bottom ends, and coupling protuberances 39 are formed on the basal plane of each of the turned-down portions so as to be easily assembled to a printed circuit board (not shown).
  • the turned-down portion 37 is formed only in either plane portion 36 in an intenna according to the embodiment of Fig. 5. This can be used if it is not necessary to use both coupling protuberances 39 when assembling on the printed circuit board.
  • a plane-shaped connecting portion 38 is formed between a pair of plane portions 36.
  • This connecting portion 38 plays a role of mitigating the bending of rod wire when rod wire 40 is arranged extending from the plane portion 36 of one side to the plane portion 36 of the other side.
  • bosses 31 are also formed in this connecting portion 38 so as to help introduction and fixing of rod wire 40.
  • intennas very simply and easily by making the base of intenna with synthetic resin material, forming a plurality of bosses that repeat continuously at a given gap on the surface of the intenna, and configuring rod wire between these bosses in such a way that rod wire is bent and fixed together in fusion. It is also possible to greatly contribute to reduction of the production cost through automation of the production process.
  • the intenna of a model in which both plane portions are formed in V shape is provided with V-shaped planes, it prevents reflection of radio waves. Therefore, it has an advantage that radio waves can be received more stably as well as the radio wave reception sensitivity is increased.

Abstract

La présente invention concerne une antenne, et notamment une antenne dont la base est constituée d'une résine synthétique, une pluralité de bosses étant formées de manière continue et répétitive au niveau d'un espace donné sur la surface de chaque partie, des fils étant pliés en vue d'une fixation par fusion entre ces bosses, d'où une fabrication considérablement facilitée parallèlement à un raccourcissement du processus de production ainsi qu'à une baisse du coût de production. Cette antenne comprend une base formée par moulage par injection de la résine synthétique. Une pluralité de bosses sont formées de manière continue et répétitive au niveau d'un espace donné sur chaque surface de la base. Un fil est plié selon une forme donnée le long de l'espace entre lesdites bosses, une extrémité de ce fil étant connectée à une borne tangentielle située sur un côté de la base.
