Datasheet microSplatch ANT-868-uSP410 Embedded 868 MHz LPWA Antenna The microSplatch uSP410 868 MHz antenna is a surface-mount monopole antenna for embedded Sub-1 GHz and low-power, wide-area (LPWA) applications including LoRaWAN , SigFox , remote controls, and ISM applications in the 862 MHz to 876 MHz range. uSP410 series monopole antennas use a grounded-line technique to achieve outstanding performance in a compact surface-mount package. The uSP410 series exhibits low proximity effect, making it a good embedded antenna choice for devices typically subject to nearby interferers. uSP410 series antennas are available in tape and reel packaging and are designed for reflow-solder mounting directly to a printed circuit board for high- volume applications.

As a best practice, Linx may use ESD packaging. Electrical specifications and plots measured with a 38 mm x 84 mm (1.5 in x 3.3 in) reference ground plane. VSWR Figure 1 provides the voltage standing wave ratio (VSWR) across the antenna bandwidth. VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna. VSWR response typically shifts lower in frequency when the antenna is in proximity to an enclosure or printed circuit board. By allowing for this shift in the antenna design, the need for complex matching circuits is reduced. 5 40 4 30 3 20 2 10 1 0 860 861 862 863 864 865 866 867 868 869 870 871 872 873 874 875 876 877 878 Frequency (MHz) Figure 1.
