Embodiment Construction

[0021] Figure 1a shows an antenna group of a mobile phone. For example, the antenna group comprises a metallization 1 supported by a support 2 such as plastic or ceramic. The radiation zone 1 is thus obtained by depositing, in particular metal vapor deposition, followed by etching of the metallized layer, in order to achieve in said metallized zone a favorable resonance and thus a favorable emission or reception of certain spectral components diagram. The spectral components are exactly the above components.

[0022] To this end, the radiation zone 1 comprises a first offset H-pattern 3 . In addition, FIG. 1b also shows the graph. In said figure 3, a metallized reed tongue 4 (tongue languette) and a further metallized reed tongue 5 are arranged in a straight line, but spaced apart from each other. The two reed tongues 4, 5 are located on the two side edges of the two etching grooves 6 and 7. The lengths of the two etching grooves are roughly equal, and they are connected ...

Abstract

In order to create a compact antenna block a corner-shaped support is provided with a radiating area on an upper surface thereof and a transition area is provided on an underlying surface. The transition area is characterized in that it is triangular. The angle of the triangle forms a connection point for the antenna. The tapered part of the corner-shaped support is fitted with a pole enabling it to be lifted above the plane of the circuit to which the antenna block is connected, whereby the transition area extends gradually above said plane, the upper radiating area being substantially parallel to said plane. As a result the impedance of the antenna can be regulated more easily in such a way that it is continuously constant and the reflection coefficient is improved.

Description

technical field [0001] The object of the present invention is to propose a particularly small antenna set for a wireless device, especially a mobile phone. It is also the object of the invention to propose a wireless device for an information network, in particular via transmission according to the Bluetooth standard. The antenna group of the invention can be used with one or the other of several frequencies, even including frequencies successively one after the other. The purpose of the present invention is mainly to simplify the realization of the radiating device and the antenna group, at the same time expand its spectrum performance, and make it have good matching in the medium that must be radiated. Background technique [0002] In the field of mobile telephony, especially in Europe, the so-called GSM standard at 900 MHz and the DCS standard at 1800 MHz are known. The frequency bands are thus significantly different, and the frequency bands in which a mobile phone mus...
