Roke Manor adds CTIA mobile antenna testing facility

LONDON — Roke Manor Research, the Siemens electronics research and development business, has invested £200,000 in the UK’s first mobile antenna testing facility to be accredited capable of meeting the Cellular Telecommunications and Internet Association (CTIA) testing requirements.

Mobile handset manufacturers who want to sell handsets in the United States have a legal requirement to undergo the CTIA’s over-the-air antenna performance testing.

EMV, an EMC test equipment specialists provided the system and software for the chamber, which was installed at Roke Manor’s headquarters in Romsey, Hampshire by ETS-Lindgren.

The tests carried out in the facility examine the connectivity of the handset, the quality of an antenna’s transmission and reception signals and detect manufacturing faults.

Martin Wiles, senior RF engineer at ETS-Lindgren, said, “Over-the-air measurements are a new addition to the test and measurement requirement of the mobile handset market and require a dedicated facility such as the one we have installed at Roke Manor. The CTIA is currently the only organisation which produces over-the-air performance tests. Although these standards are not yet enforced in Europe and Asia, new test methods and performance criteria are expected to become mandatory in the near future.

The chamber itself can be used up to 100GHz but the facility is optimised for mobile handset antenna testing. Roger Hopper, principal group manager at Roke Manor Research, said, “We currently have six projects undergoing testing in the chamber and are in the process of bidding for a number of high profile contracts.”
