Directional Patch Antenna w/ Adhesive Mount
Dual Band, Directional Patch Antenna "I-Bar"-type, with Adhesive Mount and cable length options to RP-SMA (male) connector.
- Directional antenna concentrates the radiation in one direction, to maximize signal strength. Adhesive Mount: Supplied with a 3M strong 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:
- 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.
- Compatible with Bluetooth devices, Wireless Access Points & other wireless devices that have RP-SMA antenna jacks.
- As Bluetooth antenna: Send or receive signal to devices in all directions (360-degree horizontal beamwidth).
- As client antenna: Connect to access points in any direction. Portable size: Easily fits in a laptop case.

TEST RESULTS for FREQUENCY RANGES:

The antenna delivers stable and consistent RF performance across the 2.4 to 2.6 GHz frequency range, maintaining functional impedance matching throughout the entire band. During testing, the VSWR remains approximately between 2.3:1 and 2.6:1, with Return Loss values around –7 to –8 dB, enabling adequate power transfer for practical applications. The behavior observed on the Smith Chart indicates a controlled and predictable impedance response, confirming the stability of the design. Overall, this antenna represents a reliable solution for wireless applications in the 2.4 GHz ISM band, such as WiFi, Bluetooth, Zigbee, and IoT, particularly in commercial and industrial environments where robustness and continuous operation are required.
