CC110L: SWRA496 antenna target impedance

Part Number: CC110L
Other Parts Discussed in Thread: CC-ANTENNA-DK2

I am implementing the miniature PCB helical antenna (19 mm x 11 mm) as described by reference design SWRA496 for use at 915 MHz.

Design Note DN038 gives an expected target impedance of ~10-j88 ohms for this antenna at 868 MHz.

Is there any further impedance data available from TI for Design Note DN038/reference design SWRA496?

Thank you.

  • DN038 is an older antenna reference design which is shorter than the antenna in CC-Antenna-DK2 #6 (SWRA496). Follow the ref design in CC-Antenna-DK2.

    The impedances are shown in Figure 28 for 868 MHz and 915 MHz.

    Regards,
