0.30 LBS

2.4 & 4.9GHz Dual Band Directional Patch Antenna with cable to U.FL connector.

AW418 is a slim flat, miniature antenna with a footprint size of 47 x 35.7 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.

AW418 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.

Flat low-profile patch antenna, with U.FL 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.
  • Connector, cable length and type can be customized for large orders.  

Compatibility with wireless standards & applications

This directional antenna's range of frequency band compatibility in the 2400MHz to 5825MHz frequency band range, its very low broadband VSWR at 2.0, and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the above applications.

U.FL Connectors Characteristics
  • U.FL female has a socket. U.FL female right-angle type is the most common U.FL connector type found on U.FL cables:  95% of U.FL cables have a U.FL female right-angle connector.
  • U.FL male has a pin and is the connector: Male U.FL is the gender that is the "jack" that is embedded directly on to a circuit board on devices such as Bluetooth boards, and ZigBee radios such as XBee, Printed Circuit Boards (PCBs) and internal mini-PCI wireless cards (even though the gender is male, it is the jack U.FL connector. Hence the male connectors / jacks are very rigid. 
  • The small size of U.FL connectors has made them an excellent fit in Machine-To-Machine (M2M) and IOT (Internet of Things) wireless applications, since they take up very little space in the cramped cases of small devices, such as Bluetooth beacons.
  • Gender Determination: Micro-connectors such as U.FL have gender that is counter to typical RF terminology for gender, in that "jack" is more typically synonymous with "female:" A U.FL jack on a board (PCB) is the male U.FL, and the connector that mates with the jack is the female. 
  • Connecting and disconnecting U.FL connectors from the jack can be difficult to do properly without damaging the U.FL connector or jack.  We offer a U.FL insertion tool to enable you to connect/insert and remove/disconnect easily, without causing any damage to the cable, connector or jack.
  • U.FL connector is also known as Ultra Miniature Coax Connectors (UMCC), and enables attaching an external antenna to a U.FL jack/connector on Printed Circuit Boards (PCBs): U.FL female mates with a female HiRose/U.FL jack, also known as U.FL-LP-66 jack/connector.

U.FL Connectors' Material composition

  • Male has a silver-plated phosphor bronze made the shell, and a gold-plated brass made contact.
  • Female: The shell and contact of Female U.FL connectors are made of phosphor bronze but are silver, and gold-plated respectively. Female U.FL connectors are the ones used in the termination of antenna cable.
  • U.FL connectors are precision machined. The gold-plating enables low signal loss.


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

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