Abstract

The invention discloses a measuring device, system and method for wirelessly measuring radiation patterns. An inventive measuring device comprises a measuring unit, a communication unit and a control unit. The measuring unit is adapted to wirelessly receive a measuring signal transmitted by a device under test. The control unit is adapted to derive at least one measuring device, especially a signal level, from the received measuring signal. The communication unit is adapted to only wirelessly transmit the at least one measuring result to a central measuring unit, not being part of the measuring device.

Description

technical field [0001] The invention relates to a measuring device, a measuring system and a measuring method for measuring the radiation pattern of a device under test, especially a mobile phone. Background technique [0002] In order to measure the radiation pattern of a mobile phone, a hitherto complex measurement setup was necessary. In a shielded test chamber, one or more antennas are arranged around the device under test. While the device under test is radiating, the one or more antennas are moved relative to the device under test so that measurements can be made from all directions. Each measuring antenna is connected to a measuring device which measures the received signals and processes them. The antenna is connected to the measurement equipment using a cable connection. This creates scatter from the cable connection, which must be suppressed or prevented so as not to affect the measurement. This is done by using absorbent material. Consequently, a very complex...
