Benchmarking of Facilities for Measuring Small Mobile Terminals and their Antennas: Results of a Round Robin Test in ACE

The paper presents the test cases defined in ACE (European Antenna Centre of Excellence) for benchmarking of facilities for measuring small mobile terminals and antennas, as well as the results of the first round robin test. The emphasis is put on measurements in the most popular communication frequency bands. Several test cases for passive antennas as well as for active devices were defined and collected in a test kit that was sent to different test facilities around Europe in the round robin test. The measured parameters include till now radiation efficiency and total radiated power, but in future tests the same test devices will be used for benchmarking diversity gain and receiver sensitivity. The test cases include different locations of the test devices relative to a lossy cylinder that has dielectric characteristics resembling that of a human head
