METHOD OF CHECKING THE INTEGRITY OF AN ANTENNA ARRANGEMENT, TRANSMITTER, RECEIVER AND TRANSCEIVER

摘要

In a method of checking the integrity of an antenna arrangement (2) of a transmitter (1), which transmitter (1) comprises a transmitter driving stage (4) for driving the antenna arrangement (2) with a driving current (is), a first value (I_supply) indicative of the driving current (i_s) is determined. After that, it is detected whether the driving current (i) is outside a predefined current range by comparing the first value (I_supply) with a predefined first value range. If the first value (I_supply) is outside the first value range, then it is indicated that the antenna arrangement (2) is not in sound condition. The antenna arrangement (2) is comprised of an antenna (5) and a tuning network (6) connected between the antenna (5) and the transmitter driving stage (4).
