Abstract
Official abstract text for this publication.
A field device having a metal housing, a connection line guided through a cable bushing and a radio module having an antenna, wherein the antenna extends, at least in sections, outside of the housing parallel to the connection line and in the cable bushing.
First claim
Opening claim text (preview).
We claim: 1. A field device having a metal housing, a connection line guided through a cable bushing, and a radio module having an antenna, wherein the antenna extends, at least in sections, outside of the housing, parallel to the connection line and in the cable bushing, wherein the antenna is completely arranged in the cable bushing and the antenna is overmolded with the cable bushing. 2. The field device of claim 1 , wherein the antenna is configured as λ/4 or λ/2 dipole antenna as a. 3. The field device of claim 1 , wherein the antenna is configured as a rod antenna. 4. The field device of claim 1 , wherein a portion of the connection line is connected to the radio module and used as an antenna. 5. The field device of claim 4 , wherein a shield of the connection line is connected to the radio module and used as an antenna. 6. The field device of claim 5 , wherein the shield is grounded to the housing via a frequency-selective circuit. 7. The field device of claim 6 , wherein the frequency-selective circuit is configured such that it is high-ohmic at a transmitting and receiving frequency of the radio module. 8. The field device of claim 1 , wherein a transmitting and receiving frequency of the radio module lies between 400 MHz and 10 GHz. 9. The field device of claim 1 , wherein a transmitting and receiving frequency of the radio module lies between 2 GHz and 8 GHz. 10. The field device of claim 1 , wherein the antenna is configured as a λ/4 or λ/2 wire stub antenna.
