Abstract

1. Name of the product in this design: Anti-interference antenna (time synchronization type). 2. Application of this design: This design is for a timing-type anti-interference antenna that supports signal reception at BeiDou B1 / B2 / B3 navigation frequencies. Its applications include: 1. High-precision positioning using multiple frequencies (B1 / B2 / B3); 2. Resistance to broadband, narrowband, pulse, and Gaussian interference at the B1 frequency, supporting simultaneous resistance to interference from three directions; 3. Support for expanded anti-interference functionality at the B3 frequency; 4. Interference detection function; 5. Protection against wide voltage input, overvoltage, and reverse connection. 3. The key design feature of this product is its shape. 4. The image or photograph that best illustrates the design's key points: 3D view 1.
