Description

description

Two-way radio with a housing, m which is integrated a mold for ¬ On acceptance of an antenna element.

The market for mobile or cordless phones or other handheld wireless devices demands smaller and cheaper Gera ¬ th. The antenna of a handheld radio APPARATE is not uncommon for the space requirements of such a device crucial. Des semi antenna designs are needed that have a small footprint, easily operate in multiple frequency bands or interpretable for a broadband frequency range and m manufacturing are reasonably priced.

To solve this task complex, the invention contributes by giving a radio gem. To claim 1 having a housing, m which is integrated a mold cavity for receiving an antenna element and gem by specifying a method. In claim 16 for producing a housing for a two-way radio.

Advantageous further developments of the invention are the subject of subordinate claims.

In the following the invention will be described in more detail by means of preferred exemplary embodiments and with reference to figures.

122 thread-known antenna designs for wireless devices based on a housing with an opening through which protrudes the radiating antenna element from the housing, and a generally tubular hollow body, a so-called spout, the and which is put from the outside via the antenna and the overall hauseoffnung is attached so that a very smooth and closed connection of the housing is ent ¬ with the hollow body. The manner of attachment of the hollow body to the case raises a number of problems in terms of simple and inexpensive Hersteilbarkeit the construction.

The present invention helps the starting, by providing a construc- tion, in which a cavity mold (the so-called

Spout) is integrated for receiving an antenna element in the housing. 1 shows diagrammatically an embodiment m schematic of the present invention. The housing (102) consists of two housing parts m this example, a home overall upper shell (102b) and a Gehauseunterschale (102a). In the second housing part, which is integrated Gehauseunterschale a hollow mold (103) for accommodating a (radiating) antenna element (104).

In this mold cavity, the antenna element (104) after the

Preparation of the Gehauseunterschale be easily inserted. By means of m of these hollow shape and / or on the antenna element existing mounting structures (105) or fastening elements (106), the antenna element can be easily fixed m the mold. Such mounting structures are not strictly necessary; but they increase m many cases the reliability of the device significantly.

2 shows m schematically a preferred embodiment of the invention, wherein the crush ribs (120) for fixing a Antennenele m ents a hollow mold are provided. The antenna element is simply plugged m these crush ribs during assembly and remains there due be ¬ ner special shape or on the basis of static friction, the pen at a sufficiently high pressure, the elastic Quetschπp- preferably produced on the material of the antenna element.

In cases where m is not enough, this type of attachment from ¬, a further preferred embodiment of the invention may be useful that provides for attachment by means of a snap-in hook (121). This latching hook preferably engages a groove m m of the hollow mold and holding the antenna element thus m of the intended position. As shown m Figure 2, locking hooks can also be used m combination with crush ribs, since the latter can form a groove for the latching hook at choice of a suitable distance.

Finally, it is also possible to equip the mold (103) having a mnenliegenden Gewmαestruktur (122) m which engages an external thread of the antenna element (104). Figure 4 shows this embodiment of the invention. Which type of attachment is chosen depends on different criteria from. A thread structure has the advantage that removal of the antenna element from the mold, for maintenance purposes, as is always easy.

The antenna element, which represents the actual radiating antenna in an electromagnetic sense, can be electrically connected in different ways with the two-way radio. To ensure proper electrical contact, it is advantageous to equip the antenna element at a location with a contact element or a contact surface. In this way, contact problems due to tolerances in the assembly of the radio m can avoid many traps. In this context, it is often useful to provide a contact surface on an elec- tric module of the transceiver, with the contacted by the contact element or the contact surface of the antenna element preferably directly. If this is for constructional reasons is not possible or not reliable enough, one can see a contact spring for producing a sufficiently secure connection between the antenna element and an electrical component of the radio apparatus in front ¬, on the one hand with the contact element or the Kon ¬ clock flat of the antenna element, on the other hand with Kon ¬ clock flat assembly of electrical contacts. The spring may be, for example aufgelotet on the module. However, the contact spring can also be fixed at one end of the antenna element.

The antenna element itself can be realized in any conceivable form, for example as a wire antenna, a rod antenna, lixantenne as He, or by suitably shaped strip conductor structures on an electrical assembly (so-called PCB-antenna). Further, a stamped and bent antenna or an antenna element m consideration that m the form of a conductively coated nichtleitfahigen wearer is formed is (MID) antenna.

The mold (103) can be filled with a dielectric filler material before or after the mounting of the antenna element so that the antenna element of filler material is completely or partially embedded m. Preferably, here come LIQUID materials used, which has hardened, after a certain time.

A housing or housing part for a two-way radio with a erfmdungsgemaßes inventive shaped hollow form can be a corresponding shape are made in a simple manner by pouring or injecting a plastic solid material has hardened, by m. A tubular hollow shape for receiving an antenna element can be a single operation are made together with a housing part or all of the housing using a corresponding shape m. In another process variant inventive shaped m a first working step is first prepared, the housing (102) or a housing part (102a) without a hollow mold (103) or without egg ¬ ne complete hollow mold (103a). In a second step, an antenna element (104) to said housing or housing part is then attached, and m is a drit ¬ th step is injection-molded around the antenna element (104) with a plasticized ¬ rule material or cast around it, wherein a completeness, ¬-ended hollow mold is formed which surrounds the antenna element (104).

In a further inventive shaped variant of the method a first step is first prepared m the housing (102) or a housing part (102a) without a hollow mold (103) or without a complete hollow mold (103a). In a second step, an antenna element (104) is attached to said housing or housing part then. In a third step a further shaped part (103b) as to the antenna element (104) or on the housing or housing part is mounted, in that subsequently a complete hollow mold surrounding the antenna element.

When using the last two variants of the process it is easily possible, auszufuhren an intermediate step between the second and the third step, in which the antennas nenelement (104) is first at least partially with a dielectric filler material (119) cast around or encapsulated.

Figure 5 shows a further variant embodiment of the invention in which the mold (103) for receiving a nenelements antennas (104) comprises two parts (103a, 103b) is made. The antenna element is the first tul- lenteil from above or below m (103a) is inserted, on which the antenna element can also be secured. The contact element can also be fixedly connected to the antenna element, or be part of the arrival antenna elements or be attached to the assembly. The first Tullenteil (103a) may also be part of the housing (102) or to the chassis. The second spout member (103b) may be formed as a cap or lid, which or only a small part of the antenna element can enclose up to almost the entire antenna element depending on the embodiment. To the antenna element can also be a PCB, a wire, a helix or a stamped and bent antenna, to be fixed to a spout are above implementation variants used.
