Microstrip Patch Antenna Calculator Direct

# Calculate effective permittivity effective_permittivity = (substrate_permittivity + 1) / 2 + (substrate_permittivity - 1) / 2 * (1 / math.sqrt(1 + 12 * substrate_thickness / wavelength))

return "Width (mm)": W * 1000, "Length (mm)": L * 1000, "Effective Epsilon": epsilon_eff, "Inset Depth y0 (mm)": y0 * 1000 microstrip patch antenna calculator

These antennas are favored in modern electronics, from IoT devices to 5G arrays, because they are low-profile, inexpensive to manufacture, and can be printed directly onto a Printed Circuit Board (PCB) . Core Input Parameters The depth $y_0$ is calculated using: $$R_in(y=0) =

# 3. Calculate Extension Length (delta_L) delta_L = 0.412 * substrate_height * (((epsilon_eff + 0.3) * (ratio + 0.264)) / ((epsilon_eff - 0.258) * (ratio + 0.8))) "Length (mm)": L * 1000

To achieve a 50$\Omega$ match, we use an "inset feed" (a notch cut out of the patch). The depth $y_0$ is calculated using: $$R_in(y=0) = \frac12G$$ (Where $G$ is the conductance of the radiating slot).
