Improving Antenna Efficiency | 5 Proven Methods
Improving antenna efficiency involves optimizing design and materials. Use high-conductivity metals like copper (5.8×10⁷ S/m) to reduce resistive losses. Minimize dielectric losses with low-loss substrates (e.g., Rogers RO4350B, εᵣ=3.48, tanδ=0.0037). Proper impedance matching (VSWR <1.5) enhances power transfer. Ground plane optimization (λ/4 size) reduces surface waves. For patch antennas, increasing substrate thickness (3-5 mm) improves […]
