La figura 1 muestra una antena -1-que comprende un encapsulado -2-y una tarjeta de Figure 1 shows an antenna -1-comprising an encapsulation -2-and a card of
15 circuito impreso -3-(también conocida como PCB, por la expresión en inglés “Printed Circuit Board”) estando los componentes interiores de la antena embebidos en dicho encapsulado -2-. En realizaciones particulares de la presente invención, el encapsulado -2-puede ser una cubierta previamente moldeada o puede ser un encapsulado al vacío realizado sobre los componentes ya dispuestos en la tarjeta de circuito impreso. 15 printed circuit -3- (also known as PCB, for the English expression "Printed Circuit Board") the interior components of the antenna being embedded in said encapsulation -2-. In particular embodiments of the present invention, the -2-encapsulation may be a pre-molded cover or it may be a vacuum encapsulation performed on the components already arranged on the printed circuit board.
20 Las figuras 2 y 3 muestran un despiece de la antena -1-. En esta realización, la antena comprende una base, un núcleo, y tres devanados. En particular, la base es una tarjeta de circuito impreso o PCB -3-, alrededor del núcleo -4-se disponen: un primer devanado -41orientado en dirección del eje de abscisas “X”, un segundo devanado -42-orientado en 20 Figures 2 and 3 show an exploded view of the antenna -1-. In this embodiment, the antenna comprises a base, a core, and three windings. In particular, the base is a printed circuit board or PCB -3-, around the core -4-are arranged: a first winding -41 oriented in the direction of the abscissa axis "X", a second winding -42-oriented
25 dirección del eje de ordenadas “Y”, y un tercer devanado -43-orientado en una dirección del eje “Z” y sobre este conjunto núcleo-devanados se dispone un material de encapsulado -2que, preferentemente, es de polímero plástico de altas prestaciones térmicas. 25 direction of the "Y" ordinate axis, and a third winding -43-oriented in a direction of the "Z" axis and on this core-winding assembly there is an encapsulation material -2 which, preferably, is made of high plastic polymer thermal performance
En cuanto a la PCB -3-, ésta comprende entre seis y doce metalizaciones. En esta As for the PCB -3-, it comprises between six and twelve metallizations. In this
30 realización particular, la PCB -3-comprende seis metalizaciones -31-, -32-, -33-, -34-, -35-, -36-en el contorno de su superficie superior que además se extienden total o parcialmente por la superficie lateral de la PCB a fin de que cuando esta antena se incorpore a otro sistema, las conexiones no queden únicamente por la parte inferior de la placa, sino que dichas conexiones sean visibles y pueda realizarse una inspección óptica automática In particular, the PCB -3- comprises six metallizations -31-, -32-, -33-, -34-, -35-, -36- in the contour of its upper surface which furthermore fully or partially extend through the side surface of the PCB so that when this antenna is incorporated into another system, the connections are not only on the bottom of the board, but these connections are visible and an automatic optical inspection can be performed
35 automatizada (AOI) para determinar una correcta soldadura. 35 automated (AOI) to determine a correct weld.
Si las conexiones se realizaran únicamente en la parte inferior (como en los dispositivos de la técnica anterior) se requeriría una inspección más compleja que comprendería la realización de mediciones para determinar la continuidad entre las conexiones realizadas. If the connections were made only at the bottom (as in the prior art devices) a more complex inspection would be required that would include measurements to determine continuity between the connections made.
Tal y como se observa en detalle en la figura 3, la metalización -31-está conectada eléctricamente a otra metalización -311-que se dispone en la parte interior de la PCB -3-. De manera similar, las metalizaciones -32-, -33-y -34-se encuentran conectadas a las metalizaciones -321-, -331-y -341-respectivamente. As can be seen in detail in Figure 3, the metallization -31- is electrically connected to another metallization -311- which is arranged inside the PCB -3-. Similarly, the metallizations -32-, -33-and -34-are connected to the metallizations -321-, -331-and -341-respectively.

Volviendo a la figura 2, estas metalizaciones unidas a los devanados corresponden con las metalizaciones -311-, -321-, -331-, -341-de la PCB -3-. Como resultado se obtiene una conexión robusta entre los devanados orientados en las direcciones de abscisas “X” y ordenadas “Y” durante todo el proceso de ensamblaje de piezas y la conexión entre devanados y PCB se realiza mediante la soldadura de piezas coincidentes, lo que elimina la necesidad de conexión de terminales que, habitualmente, tiene un alto componente no-automatizable. As can be seen in greater detail with reference to Figure 4, the core -4 has metallizations -40-at the vertices of its lower surface, these metallizations -40-are joined by welding to each of the ends of the windings and In this way, a single piece without loose cables is available, including core windings and connections. Returning to Figure 2, these metallizations attached to the windings correspond to the metallizations -311-, -321-, -331-, -341-of the PCB -3-. As a result, a robust connection is obtained between the windings oriented in the directions of abscissa “X” and ordered “Y” during the whole process of assembling parts and the connection between windings and PCB is made by welding matching parts, which eliminates the need for connection of terminals that usually has a high non-automatable component.
Las metalizaciones -40-se unen al núcleo -4-, preferentemente, mediante baños químicos y dichas metalizaciones son, preferentemente de estaño Sn100 para facilitar su soldadura a la PCB -3-. The metallizations -40-are joined to the core -4-, preferably, by chemical baths and said metallizations are preferably tin Sn100 to facilitate welding to the PCB -3-.
Por otra parte, las metalizaciones laterales -35-, -36-de la PCB -3-están dispuestas de manera tal que, una vez dispuesto el devanado orientado en la dirección del eje “Z”, se conectan sus extremos a la PCB mediante soldadura.

Por ejemplo, se pueden disponer derivaciones de cualquiera de los devanados en un punto intermedio de estos funcionando esta derivación como antena de alta frecuencia estas derivaciones se podrían conectar, posteriormente, a metalizaciones adicionales que disponga la PCB. En una realización especialmente preferente, cada uno de los devanados In particular embodiments of the present invention, the PCB may have additional metallizations along its contour without involving any inventive activity. For example, derivations of any of the windings can be arranged at an intermediate point of these, this derivation operating as a high frequency antenna, these derivations could subsequently be connected to additional metallizations provided by the PCB. In a particularly preferred embodiment, each of the windings
comprende una derivación de manera que se obtiene una antena tridimensional tanto a alta como a baja frecuencia. It comprises a shunt so that a three-dimensional antenna is obtained at both high and low frequency.

In addition, the present invention comprises the arrangement of high frequency antennas embedded in the PCB -3 - either as printed circuit tracks or as metal embossments.
En cuanto a materiales de fabricación, el núcleo suele ser un núcleo de ferrita, en concreto, un núcleo de Níquel-Zinc o Manganeso-Zinc. Otras realizaciones podrían incorporar un núcleo de Cobalto amorfo. Los devanados son, preferentemente de un diámetro entre 0.01 mm y 1 mm y pueden ser cables de cobre preferentemente esmaltados con poliuretano y/o poliamida con un índice de calor superior a los 150oC. As for manufacturing materials, the core is usually a ferrite core, specifically, a Nickel-Zinc or Manganese-Zinc core. Other embodiments could incorporate an amorphous Cobalt core. The windings are preferably of a diameter between 0.01 mm and 1 mm and can be copper cables preferably enameled with polyurethane and / or polyamide with a heat index greater than 150 ° C.

Dado que se disponen las metalizaciones en la parte inferior del núcleo el montaje de estos dos núcleos con sus respectivos devanados no tiene elementos externos para conexión, lo que no solo facilita el montaje del núcleo a la PCB sino que además le proporciona una mayor estabilidad, disminuyendo la cantidad de conexiones con elementos más frágiles como lo son los devanados. Since the metallizations are arranged in the lower part of the core, the assembly of these two cores with their respective windings does not have external elements for connection, which not only facilitates the assembly of the core to the PCB but also provides greater stability, decreasing the amount of connections with more fragile elements such as the windings.
Además se observa la disposición de puntos de adhesivo -37-a los que se unirá el devanado -43-correspondiente a la orientación del eje “Z”. In addition, the arrangement of adhesive points -37-to which the winding -43-corresponding to the orientation of the "Z" axis is observed.
