2.4 GHz Directional Patch Antenna with cable to connector options: RP-SMA female and SMA-female.

Flat low-profile patch antenna, with RP-SMA male connector. Includes a strong adhesive pad so that you can easily mount it in the best position / location for minimal obstruction and optimal signal strength.

  • Directional antenna concentrates the radiation in one direction, to maximize signal strength.Adhesive Mount: Supplied with a 3M stong adhesive base strong adhesive, enabling simple installation. This antenna perfect for quick and simple installations onto surface materials such as metal, glass, wood and plastic.
  • 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.
  • Directional, direct connect antenna tuned to perform on 2.4GHz networks. 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.

Compatibility with wireless standards & applications: This omni directional antenna's range of frequency band compatibility in the 2.4 ~ 2.5GHz frequency band range, its its excellent low broadband VSWR at < 1.6, and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the following applications:  

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 very low broadband VSWR at < 1.6, and impedance matching to 50 Ohm gear makes it suitable and compliant for all the above applications.

RP-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 have threads on the 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


A2P2 is a slim flat, miniature antenna with a footprint size of 35.5 x 39.9 mm: This antenna will fit discreetly onto most surfaces, whether that is on an enclosure wall or on the side of a wireless router. The adhesive pad eliminates the need to drill holes or apply adhesive substances - simply ‘peel & press’ the antenna into its desired position.

A2P2 is tuned to operate within the 2.4GHz to 2.5GHz frequencies: Helps to improve the short range signal transmission/reception of your WiFi router, Bluetooth gadgets and low power ZigBee sensors.

Data Alliance's high-quality soldered terminations of RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.
