Antenna plug socket

摘要

In the case of an antenna plug socket having a metal housing, which socket has at least one input terminal and two coaxial output connections as well as a circuit board on which the electrical components and/or electrical connections are arranged and whose earth surface is connected to the metal housing via conductive supports, the earth surface of the circuit board is separated into two earth surface elements, each of which is allocated to one output connection and which are at the greatest possible distance apart from one another. This results in a coupling loss between the output connections of said antenna plug socket in the frequency range up to 1.75 GHz in a very simple manner and without any additional costs, which coupling loss conforms with the German Post Office recommendations for terrestrial broadcast radio transmission (RF-TV: >/= 50 dB, TV-TV: >/= 40 dB) and with those for the first satellite intermediate-frequency band (TV-TV: >/= 34 dB).
