There are seven key points in custom antenna design: 1) frequency band matching (such as 2.4/5GHz dual-band); 2) gain optimization (≥8dBi); 3) low standing wave ratio (VSWR<1.3); 4) material selection (RO4350B high-frequency board); 5) 3D electromagnetic simulation (HFSS/CST verification); 6) environmental testing (-40℃~85℃); 7) impedance matching (50Ω±5%).

When selecting an RF antenna supplier, you need to examine: 1) frequency range (e.g. 2.4-5.8GHz); 2) gain (≥5dBi); 3) standing wave ratio (VSWR<1.5); 4) material (FR4 or PTFE); 5) test report (compliant with FCC/CE standards).

In 2025, waveguide manufacturing will use nanoimprint lithography (±10nm accuracy), low-loss silicon nitride (≤0.1dB/cm), combined with PECVD deposition (300°C) and femtosecond laser cutting (roughness <50nm), with AOI inspection yield >99.8%. How to Select Materials Last month we just handled the vacuum leak incident of the APT-6D satellite’s waveguide components – the flange material’s on-orbit thermal
