Wireless antenna electronics. Close-up of a circuit board used in wireless antenna equipment. This equipment is being tested in the SMART (Small Antenna Radiated Testing) chamber at the National Physical Laboratory, Teddington, UK. This chamber is used for minimally-invasive measurements of electrically-small antennas that operate at frequencies above 400 MHz. This includes those used in familiar applications such as domestic wireless computer (WLAN or wi-fi) networks.
