2.4GHz 2dBi Internal PCB Antenna with 1.13mm (L-10CM) + UFL Connector

A 2.4GHz 2dBi internal PCB antenna is a specific type of antenna used in wireless communication, particularly for devices operating on the 2.4 GHz frequency band, which is common for Wi-Fi and other wireless technologies. Here's a detailed breakdown of its characteristics:

1. 2.4GHz Frequency:

   • Purpose: This antenna is designed to operate at the 2.4 GHz frequency band, which is commonly used for Wi-Fi (802.11b/g/n), Bluetooth, and some other wireless communication standards.
   • Band: It’s part of the ISM (Industrial, Scientific, and Medical) band that is unlicensed and widely used for various wireless applications.

2. 2dBi Gain:

   • Gain: The 2dBi indicates the antenna's gain, which measures how much power the antenna can focus in a particular direction compared to an isotropic radiator (a theoretical antenna that radiates equally in all directions). A 2dBi gain means that the antenna provides a modest increase in signal strength over an isotropic radiator.
   • Performance: A 2dBi gain is relatively low, making this type of antenna suitable for shorter-range communication or scenarios where high gain is not critical. It typically provides good coverage for small to medium-sized areas, such as within a room.

3. Internal PCB:

   • PCB (Printed Circuit Board) Antenna: This type of antenna is integrated directly into the circuit board of a device. It’s designed to be compact and cost-effective, and is often used in devices where space is limited or where external antennas are not practical.
   • Design: PCB antennas are etched onto the surface of the PCB and are generally small, making them ideal for compact electronic devices.

4. Internal:

   • Mounting: As an internal antenna, it’s embedded within the device rather than mounted externally. This helps maintain a compact design and avoids the need for external protrusions.
   • Integration: Internal antennas are commonly used in devices like smartphones, tablets, routers, and other compact electronics where external antennas would be cumbersome or visually unappealing.

• Consumer Electronics: Used in devices such as smartphones, tablets, and laptops to provide Wi-Fi or Bluetooth connectivity.
• IoT Devices: Ideal for Internet of Things (IoT) devices where space is limited and external antennas are not feasible.
• Wireless Modules: Found in various wireless modules and embedded systems where an internal antenna solution is preferred for its compactness and ease of integration.

• Benefits:

  • Compact Design: Internal PCB antennas save space and are ideal for small devices.
  • Cost-Effective: Integrating the antenna into the PCB reduces manufacturing costs and complexity.
  • Aesthetic: Eliminates the need for external antennas, contributing to a cleaner device design.

• Limitations:

  • Limited Gain: With a 2dBi gain, the antenna provides lower signal strength compared to higher-gain antennas, which may limit its effective range and performance in challenging environments.
  • Placement Sensitivity: Performance can be affected by the placement of the antenna within the device and the materials surrounding it.
