Circuit for transmitter and/or receiver with reduced construction costs for same functionality leading to reduction in production costs - has antenna(s) and associated triggering device(s) connected to transmission and/or reception unit via same conducting path

摘要

The circuit has a transmission and/or reception unit (10) connected to at least one antenna (16,16') with an associated trigger source (19,19') per antenna. The antenna(s) and the associated triggering device(s) are connected to the transmission and/or reception unit via the same conducting path. The connection of the transmission/reception unit is detected and the unit then sends or receives over the same path to the antenna.
