Inset Fed Patch Antenna Calculator -
Use these equations to build your own calculator in Excel, Python, or MATLAB.
If you are designing multiple patch antennas for an array (e.g., 2x2 or 4x4 phased array), manual entry becomes tedious. Consider these advanced options: inset fed patch antenna calculator
Microstrip Antenna Inset Feed Calculator * The feedline width required for a target impedance (generally 50 Ohms) is determined. * Altium Resources·Altium Academy Use these equations to build your own calculator
W=c2f02ϵr+1cap W equals the fraction with numerator c and denominator 2 f sub 0 end-fraction the square root of the fraction with numerator 2 and denominator epsilon sub r plus 1 end-fraction end-root : Increasing can slightly improve bandwidth and gain. Calculate Patch Length ( 2x2 or 4x4 phased array)
To match the feed line impedance ( Z_0 ) (e.g., 50 Ω): [ Z_0 = R_\textin(0) \cos^2\left(\frac\piLy_0\right) ]
