Antenna measurements constitute an indispensable part of the development, approval, or commissioning of any wireless system. The stringent specifications and high complexity of modern antennas necessitate that the characterization of these be achieved by way of measurements. This is true for analysis and synthesis in the development of antennas, for verification in the approval of antennas, and for calibration in the commissioning of antennas. The importance of antenna measurements increases with the on-going growth of wireless technologies, and it is reflected in expanding research and development activities as well as numerous new antenna measurement facilities being established.
Generally, the EurAAP working group on antenna measurements constitutes a framework for cooperation to advance research and development of antenna measurements in support of the ever-increasing use of wireless technology in modern society.
The Main Mission
Purpose of the Working Group
Specifically, the EurAAP will pursue the following long-term objectives:
Antenna measurement techniques for new wireless technologies, Standard procedures for different antenna measurements techniques, Standard procedures for benchmarking of antenna measurement facilities, Services for antenna measurement facilities and the wireless communication industry; Mobility of personnel and sharing of technical resources; Educational activities for universities and industry; Cooperation/networking with other professional organizations on antenna measurements
Also, this working group has established a long-term cooperation with the different COST actions in antenna area (specifically COST-VISTA), with the AMTA Europe Volunteer Group (Antenna Measurement Techniques Association) and with IEEE (Institute of Electrical and Electronic Engineering). The working group is organized in tasks. The on-going tasks are:
Antenna Measurement Intercomparison
Four on-going/completed campaigns with different antennas:
. BTS1940 – base-station antenna, UMTS & GSM bands, 8 participants – completed
. SH800 – ultra-wideband horn, 0.8 – 6.0 GHz, 13 participants – completed
. SR40-A – offset reflector, Ku- and Ka-bands, 10 participants – completed
. MIMO – few PIFA antennas, LTE bands, 2 participants – on going
. MVG Chip reference antennas, V band: new campaign starting now!
Support from EurAAP for shipment and insurance of the antennas
Small Antenna Measurements
This is a transversal activity between 'Antenna Measurements' working group and the 'Small Antenna' technical group, merging tasks dealing with characterization of electrically small antenna. This task is headed by L. Le Coq, from IETR.
TASK 3 New Antenna Measurement Standard
(started in 2015)
Contribution to the development of the new IEEE standard on antenna measurements (149 and 1720)
TASK 4 Measurement Facility Comparisons with mm-VAST
(started in 2019).
Campaign for comparisons in mm-bands with mm-VAST antenna to ensure accurate measurements of next generation communication antennas in K/Ka/Q/V bands. The campaign is on-going so please contact us if you want to join
TASK 5 Self-evaluation measurement
To establish a process to self-evaluate antenna measurement systems from comparison of the measurement results with the reference patterns obtained in the inter-comparison campaigns performed within Task 2. Suitable to new labs or any facility needing to do inter-comparison activities to maintain their certification.
The campaign is on-going so please contact us if you want to join.
TASK 6 New and emerging technologies for antenna OTA measurements
To promote collaborative research in new and emerging technologies for antenna OTA measurements. It started in March 2021 - on-going
