Five tips for optimizing waveguide performance: 1. Control manufacturing tolerance (±0.005mm); 2. Select low-loss materials (such as silver-plated copper tubes); 3. Optimize the bending radius (≥2 times the wavelength); 4. Use high-performance sealing flanges (VSWR<1.2); 5. Regular maintenance and cleaning (avoid oxidation that causes insertion loss>0.5dB).

Customized antenna solutions include: 1. PCB antenna (efficiency>80%); 2. Ceramic antenna (gain about 2dBi); 3. Chip antenna (size<5x5mm); 4. Helical antenna (covering frequency 700-2700MHz); 5. Flat antenna (high directivity); 6. PIFA antenna (multi-band support); 7. Yagi antenna (long-distance transmission). The choice depends on application requirements and performance indicators.

Waveguide production includes 7 key steps: 1. Design simulation (HFSS/CST software); 2. Material selection (such as aluminum, copper or ceramic); 3. Machining (CNC accuracy ±0.01mm); 4. Surface treatment (gold/silver plating, thickness ≥5μm); 5. Assembly (flange connection or welding); 6. Testing (vector network analyzer test S parameters); 7. Sealing and protection (IP67 grade). Each step requires
