Abstract

The invention relates to a module (10) for exchanging radio data, particularly mobile radio data, comprising: transmitting/receiving electronics for processing mobile radio signals to be transmitted and/or received; shielding means (12) for electromagnetically shielding the transmitting/receiving electronics, and; a transmitting/receiving antenna (22) for transmitting and/or receiving mobile radio signals. The shielding means (12) have at least one electrically conductive shielding cover (12) that encapsulates the transmitting/receiving electronics. The transmitting/receiving antenna (22) is placed in the vicinity of the at least one shielding cover (12) so that the latter serves, at least in sections, as a ground surface during the transmission and/or reception of mobile radio signals.

Claims

1. A module interchanging radio data, in at least one frequency band, comprising:

transmitting/receiving electronics to process mobile radio signals which are to be transmitted and/or to be received;

a shielding unit to electromagnetically shield of the transmitting/receiving electronics; and

a transmitting/receiving antenna to transmit and/or receiving mobile radio signals,

with the shielding unit having at least one electrically conductive shielding cover which encapsulates the transmitting/receiving electronics, and with the transmitting/receiving antenna being arranged in a region of the at least one shielding cover such that, at least in part, it acts as a ground surface during transmission and/or reception of mobile radio signals, and with the transmitting/receiving antenna being connected to the transmitting/receiving electronics via a contact spring.

2. The module as claimed in claim 1,

wherein

the transmitting/receiving antenna is in the form of a planar antenna.

3. The module as claimed in claim 2,

wherein the transmitting/receiving antenna and the ground surface lie in essentially parallel planes.

4. The module as claimed in claim 2,

wherein the transmitting/receiving antenna is provided on an antenna mount composed of electrically non-conductive material.

5. The module as claimed in claim 4,

wherein he antenna mount is fitted to the at least one shielding cover/

6. The module as claimed in claim 5,

wherein the shielding cover and the antenna mount are combined to form an integral unit.

7. The module as claimed in claim 4, wherein at least one shielding cover is in the form of a hollow body which is open on one side, and is fitted, or can be fitted, via attachment sections, which are formed on a free edge, to a printed circuit board on which the transmitting/receiving electronics are mounted.

8. The module as claimed in claim 6, wherein the at least one shielding cover and/or the antenna mount are replaceable or interchangeable.

9. A mobile radio terminal, having a radio module, the module comprising:

transmitting/receiving electronics to process mobile radio signals which are to be transmitted and/or to be received;

a shielding unit to electromagnetically shield of the transmitting/receiving electronics; and

a transmitting/receiving antenna to transmit and/or receiving mobile radio signals, with the shielding unit having at least one electrically conductive shielding cover which encapsulates the transmitting/receiving electronics, and with the transmitting/receiving antenna being arranged in a region of the at least one shielding cover such that, at least in part, it acts as a ground surface during transmission and/or reception of mobile radio signals, and with the transmitting/receiving antenna being connected to the transmitting/receiving electronics via a contact spring.
