–1 – Revised 10/18/2018 Product Description The Linx LCD Dipole Antenna is a superior solution for users searching for best-in-class performance for WLAN devices using Dual-Band WiFi (802.11ac, 802.11n, 802.11ax) or U-NII applications. With a compact package and low price, the LCD’s high peak gain and superior efficiency make it an excellent option for high volume, cost sensitive applications. Dipole design means that no additional ground plane is required. Features •Excellent performance •Dual-band •Very low VSWR •Omni-directional pattern •Tilt and swivel base •Standard SMA or Part 15 compliant RP-SMA connector Electrical Specifications Parameter Recommended Frequency Range 2.4GHz WIFIU-NII5.8GHz WIFI/ U-NII-3 Band 2.4 – 2.5GHz5.125 – 5.725GHz5.725 – 5.875GHz VSWR<2:1<2:1<2:1 Peak Gain (max in the band)2.8dBi4.5dBi2.92dBi Average Gain (typical)–0.6dBi–1.5dBi–2.2dBi Efficiency (typical)85%70%65% PolarizationLinear RadiationOmni-Directional Max Power10W Wavelength1/2-wave Impedance50-ohms ConnectionSMA Plug (Male) or RPS (Reverse Polarity Male) Weight7.4g (0.26oz.)

Linx knows how our customers most frequently use our antennas in theirs designs, typically mounted to enclosures, conductive or non-conductive, so we tested our LCD antenna in 2 different configurations: straight, without ground (free space), and edge of a ground plane bent at 90°. Linx tested the LCD dipole antenna to ensure excellent radiation behavior and minimize the risk to the customer when implementing a new design, regardless of complexity. Additionally, there are many other configurations with which our LCD antenna will have similar performance to the Bent 90°, on edge of ground, with minimal difference, as shown below.
