A Microstrip Impedance is a type of electrical transmission line used to transmit RF signals and are commonly fabricated using printed circuit board (PCB) technology. Compared to waveguides, microstrip is generally has a lower power handling capacity, and higher losses due to the fact that it is not enclosed.
The most accurate formula that address microstrip impedance is done by Hammerstad and Jensen reported in this research paper “E. O. Hammerstad and O. Jensen, Accurate models for microstrip computer-aided design. IEEE MTT-S Dig. 1980, pp. 407−409.” The accuracy of this model for is better than 0.01% for u ≤ 1 and 0.03% for u ≤ 1000. (u = W/h).
Our calculator use these equations to calculate the characteristic impedance also provides the advantage of synthesize the strip structure for a given required impedance saving time trying different parameters to reach the desired impedance value
