Patch WIFI Antenna

Key Features

1. Directional Radiation Pattern:

   • Patch antennas emit radio signals in a specific direction, making them highly effective for point-to-point or point-to-multipoint links.

   • Typical beamwidth ranges from 30° to 90°, allowing focused coverage and reduced interference.

2. Frequency Range:

   • Common models operate in 2.4 GHz (2400–2483 MHz) and 5 GHz (5150–5850 MHz) bands, supporting both 802.11 b/g/n and 802.11ac/ax (Wi-Fi 5/6) standards.

3. Gain:

   • Patch WiFi antennas usually offer gain values between 6 dBi and 14 dBi.

   • Higher gain provides longer-range coverage but narrows the beamwidth.

4. Design and Construction:

   • Consists of a flat metallic patch mounted on a dielectric substrate backed by a ground plane.

   • Compact and lightweight; ideal for wall or ceiling mounting.

   • Enclosure is typically made of ABS plastic or weather-resistant material for indoor or outdoor use.

5. Polarization:

   • Available in linear or circular polarization, depending on application.

   • Some models support dual-polarization (vertical and horizontal), enhancing performance in MIMO (Multiple Input Multiple Output) systems.
