Compact Evaluation Board for Evolution DTA.01.A Digital Tunable Antenna

The DTAD.01.A.50 is an evaluation board for Taoglas’s new patent-pending series of Evolution DTA tunable antennas. DTA antennas deliver higher efficiency on a smaller ground plane than traditional passive antennas, enabling a new miniaturized generation of high-performance wireless devices. Typical applications would be 3G On-Board Diagnostic (OBDII) devices in automotive applications, medical telemetry devices, 4G dongles, access points and routers.

The board contains a surface-mount ceramic antenna DTA.01, a tunable capacitor PE64102 DuNETM (32 state capacitance) from Peregrine Semiconductor and a matching circuit. Via a USB connection to the board, the antenna frequency response is shifted via a command from a PC with Peregrine-supplied software and driver. The antenna parameters itself can be measured via the on-board SMA connector.
