Hi,

The documentation to the Antenna kit has now been released on the internet: http://focus.ti.com/lit/an/swra328/swra328.pdf

The main purpose of the Antenna Kit is to ease the decision for which type of low cost antenna can be implemented and an estimation of the performance that can be achieved. The frequency range of the antennas is from 136 MHz to 2480 MHz. The A4 sized PCB panel contains 16 different boards; 13 antenna designs and 3 boards for calibration purposes. Each board has been v-cut and can be snapped out of the PCB panel.

All antennas are tuned for connecting to an EM board on the EB platform. A matching network is used on each antenna design so the antenna boards can matched for various GND sizes than the EB board. For each antenna, a CTIA measurement summary is provided in this report with a link to the full measurement CITA report. DN6xx is designated for CTIA measurement reports.

·       169 MHz (136 MHz - 240MHz) Antenna

·       315 MHz (273 MHz - 348MHz) Antenna

·       433 MHz (387 MHz - 510MHz) Antenna

·       868 MHz (779 MHz - 960MHz) Antenna

·       915 MHz (779 MHz - 960MHz) Antenna

·       2440 MHz Antenna

·       PCB Antenna

·       Wire Antenna

·       Ceramic Chip Antenna

·       Antenna Kit

·       Dual Band Antenna (868 MHz & 2440 MHz)

·       Mitsubishi Chip Antenna

·       Pulse Chip Antenna

·       Helical Wire Antenna

·       Pulse Helical Wire Antenna

    Hi Richard ;

    I want to ask a question about swra307a:Mitsubishi Ceramic Antenna for 868 MHz, 915 MHz & 955 MHz. On page 9 of  pdf, the ccordinate axis is given as below :

    x axis:up

    y axis : right

    z  axis : through out  PC screen

    Is  the direction of the z axis plotted wrong? For my opinion it must point inside the PC screen.

    Thank you very much

    Hi,

    DN033: will double check the coordinate axis with Mitsubishi who orginally provided the material for this report.

    In the mean time, the AMD1103-ST01T chip antenna is also used on the CC-Antenna-DK (DN031: http://www.ti.com/litv/pdf/swra328) and the coordinate axis used in the DN031 is without a doubt correct. Measurement data for CC-Antenna-DK with AMD1103-ST01T (board 3) can be found at DN600: http://www.ti.com/litv/pdf/swra329

    Regards,

       Richard.

    Hi,

     

    Just got the answer from Mitsubishi concerning the coordinates used in DN033:

    The original was not considered incorrect.  MMC used the left-handed coordinate system, which is not used often as the right-handed coordinate system is more common. The reason why MMC used the left-handed coordinate system is a simple error when they entered the coordinate axis.  By changing the original "X axis" to "-X axis", it automatically becomes the right-handed coordinate system.
     
    I hope this explanation clarifies your question.
    Regards,
       Richard.
