Introduction The DTAD.01.A.50 is an evaluation board for Taoglas new patent pending series of Evolution DTA tunable antennas. DTA antennas deliver higher efficiency on 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, medical telemetry devices, 4G dongles, access points and routers. The board contains a surface-mount ceramic antenna DTA.01, a tunable capacitor PE64102 DuNE (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. A new generation of M2M devices with as little as a 50mm ground-plane in length can now achieve wide frequency coverage and higher data rates with large bandwidth for a passive antenna with the same footprint and volume. The DTAD.01.A.50 board (60.50x45mm) with ground plane size of 50x45 mm can perform efficiently at a bandwidth from 698-960 MHz and from 1710-2170 MHz, covering all worldwide cellular 4G/3G bands in a tiny form factor. In combination with your device s microprocessor it has the ability to dynamically improve the efficiency of a given antenna band in real time. Using a combination of the DTA.01 and the PE64102 we can cover the entire bandwidth for 4G and 3G cellular bands. Using the State 03 (2.58 pF) we can cover the 700/850/1800/1900 and 2100 MHz Band only and with the State 13 (6.52) pF we can cover a penta-band solution 850/900/1800/1900 and 2100 MHz. The optimal states will change depending on the ground-plane, device s board and mechanical environment. SPE-13-8-041/B/RC Page 2 of 25
