Antennas

Commercial radio technology has reached an inflection point, similar to the transition from analog to digital, when we invented a whole range of digital technology; now we’re moving from single carrier technologies, where we transmit one digital symbol at a time, to a new paradigm, where we’re potentially transmitting hundreds of symbols simultaneously.

RF susceptibility or immunity test systems are often configured as dynamic hardware solutions that address more than one of the ever changing EMC standards. Automation by way of a software driven RF test system controller provides signal routing switch matrices and improves test reliability and engineering productivity.

Two trends are well underway in portable and handheld consumer electronic devices: shrinking form factors and the integration of multiple wireless technologies, such as Bluetooth™, cellular, GPS and Wi-Fi. These trends create challenges for device vendors and integrators by increasing the likelihood of RF noise and other system interactions that can undermine antenna performance.
