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: BluetoothZigBee, 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
  • 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.

RP-SMA and SMA Connector Characteristics

  • RP-SMA = Reverse Polarity SMA. Also known as SMA-RP, SMA-R, SMA RP, SMA R.
  • RP-SMA and SMA gender is counter-intuitive: The gender is referring to the pins inside-not the threads. RP-SMA male has threads on inside. More details regarding RP-SMA gender determination
  • RP-SMA-male and SMA is also called "plug" and the respective female connectors are also called a "jack." 
  • RP-SMA and SMA are round screw-type connectors, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.
  • Composition
    • Connector Body: Brass, Gold Plated for low loss. Precision-machined.
    • Center Contact: Beryllium Copper, Gold Plated
    • Crimp Ferrule: Copper, Nickel Plated
    • Insulators: PTFE
  • We offer an SMA wrench to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
  • SMA-male connector fits items that have an SMA (female) jack/connector.
  • Gender of SMA is counter-intuitive: Please observe picture & note it is correct.


All of our antennas pass QC test before we ship them.
