Basic properties of a quarterwave monopole antenna

WebThe antenna is fabricated on a standard 1.6mm FR4 substrate material with a typical dielectric constant ε r of 4.4 at 900MHz. The width of the monopole trace is W = 1.5mm. The wavelength in free air is λ 0 = 333mm. It may be approximated that the guided wavelength λ g on the FR4 substrate is about λ g ˜ 0.75 · λ 0 = 0.75 · 333mm ˜ 250mm WebFor these designs, FR4 is not an ideal choice — FR4 has a higher Df, or dissipation factor, than high-frequency laminates. This means FR4 circuits will suffer more signal loss than an identical circuit on a high-frequency laminate. The Df of FR4 is around 0.020, while the Df of most high-frequency laminates is around 0.004, a fourth of FR4 ...
