Embedded Active Dual Band GNSS L1/L2 GPS Internal PCB Antenna

An embedded active dual-band GNSS L1/L2 GPS internal PCB antenna is designed for applications where space is limited, and you need an antenna that can be integrated directly onto a printed circuit board (PCB). Here's a detailed overview of this type of antenna:

1. Frequency Bands:

   • L1 Band: Operates around 1.575 GHz, commonly used for GPS signals.
   • L2 Band: Operates around 1.227 GHz, also used for GPS signals and often for military or high-precision applications.

2. Active Antenna:

   • Built-in Amplifier: An active antenna includes an internal amplifier to boost the received signal. This can improve performance, especially in environments with weak signals or interference.

3. Embedded Design:

   • Internal PCB Mount: Designed to be mounted directly onto a PCB, which is ideal for compact devices and applications where external antennas are impractical.

4. Dual-Band Capability:

   • L1/L2 Support: The antenna is capable of receiving signals on both the L1 and L2 bands, allowing for better accuracy and robustness in GNSS applications.

5. Connector:

   • Direct Connection: Usually, the antenna connects directly to the PCB without the need for external connectors. Ensure that the antenna's design is compatible with your PCB layout.

6. Size and Form Factor:

   • Compact: These antennas are typically small and designed to fit within the constraints of a PCB, making them suitable for portable and embedded devices.

7. Performance Specifications:

   • Gain: Check the gain specification to understand how well the antenna will perform. Higher gain usually translates to better reception.
   • Noise Figure: An important parameter for active antennas, indicating the level of noise introduced by the antenna's amplifier.

1. PCB Design:

   • Ensure the PCB design includes the necessary footprint and solder pads for mounting the antenna.
   • Consider the antenna's placement to avoid interference from other components and ensure optimal signal reception.

2. Power Supply:

   • Active antennas require a power supply for the internal amplifier. Ensure your design includes the necessary power connections and check the voltage and current requirements.

3. Signal Integrity:

   • Use high-quality PCB materials and ensure proper impedance matching to maintain signal integrity between the antenna and the GNSS receiver.

4. Testing and Calibration:

   • After integration, test the antenna performance to ensure it meets your requirements. Calibration may be necessary to optimize performance in your specific application.

5. Environmental Considerations:

   • Verify that the antenna is suitable for the environmental conditions of your application, including temperature and humidity.

• Embedded Systems: Ideal for use in devices where space is at a premium, such as handheld devices, wearables, or automotive systems.
• Consumer Electronics: Suitable for GPS-enabled electronics where an external antenna is not feasible.
• Industrial Equipment: Used in equipment that requires accurate positioning in a compact form factor.
