Antenna 4G+ LTE-A

thingiverse

It's a custom-designed log parabolic antenna for use with 4G routers, covering the frequency range of 800-2700 MHz. The design was created using http://hamwaves.com/lpda/. To build this antenna, you'll need to source copper wire with a diameter of 1.5mm, similar to what's found in electrical cables. The design was modeled using SolidWorks software. INPUT Lowest frequency f₁ = 800 MHz Highest frequency fₙ = 2700 MHz Diameter of the shortest element ⌀ = 100 mm Characteristic input impedance Z₀ᵢ = 50 Ω Taper τ = 0.880 Optimal relative spacing σₒₚₜ = 0.163 Chosen relative spacing σ = 0.060
