Bluetooth WiFi Embedded Patch w/ RP-SMA or SMA
2.4GHz Directional Patch Antenna with connector options: RP-SMA female and SMA-female.
- Can be used for embedded product design.
- Generally used inside of a casing but can be screw-mounted as-is, in a protected mounting-spot.
PCB antenna, flat low-profile, with options for RP-SMA female and SMA female connectors. Generally used inside of a casing or enclosure, but can be screw-mounted externally, or mounted with an adhesive such as double-sided foam tape, in a spot where it will not be disturbed. [See also: Version of this antenna inside of an ABS casing with cable to RP-SMA connector].
- Directional antenna concentrates the radiation in one direction, to maximize signal strength.
- The limited beamwidth reduces "signal noise" / interference from other WiFi networks and third-party wireless devices, resulting in much greater performance of the device connected to this antenna (especially as compared to omni-directional antennas, which pickup 360-degrees of signal noise.
Compatibility with wireless standards & applications:
- IoT wireless & M2M: Bluetooth, ZigBee, Wi-Fi HaLow and ISM. Since it is vertically polarized, it is compatible with many machine to machine communication applications, remote monitoring, and telemetry applications.
- 2.4GHz WiFi applications: 802.11N, 802.11G, 802.11B, 802.11AH.
- Linear polarized, it is suitable for many of today’s machine to machine and communication applications such as telemetry, remote monitoring and mesh networking applications.
- Directional, direct connect antenna tuned to perform on 2.4GHz networks.
Suitable and compliant for all the above applications because of this antenna's range of frequency band compatibility in the 2.4 ~ 2.5GHz frequency band range, its low broadband VSWR, and impedance matching to 50 Ohm gear.
