Layout & Installation Notes:

• PCB Placement: For optimal performance, the antenna should ideally be placed at the center of the host PCB's longest edge.

• Matching Circuit: Requires a simple 3-component matching network architecture close to the feed to ensure precise tuning (typically utilizing a 2.2pF tuning capacitor at E2).

• Pin Configuration: The antenna features 6 pads; Pin 2 is the active RF Feed, while Pins 3, 4, and 6 are Grounding connections. Pins 1 and 5 are non-conductive and used strictly for mechanical strength.

Frequently Asked Questions: Q1: Does this antenna require an external ground plane to function? A1: Yes. To achieve the high efficiency and peak gain specified in the datasheet, this SMD GNSS antenna must be integrated with an appropriate host PCB layout (ideally placed at the center of the longest edge) and a matching circuit.

Q2: Can this antenna receive multi-constellation signals simultaneously? A2: Yes. The wide frequency range of 1559 MHz to 1609 MHz covers the essential bands for GPS, GLONASS, Galileo, and Beidou, allowing modern GNSS receivers to utilize multiple satellite networks at the same time for faster and more accurate positioning.
