Microstrip Coupler with Capacitor Compensation

Here we keep things simple and add up to three lumped capacitors to a parallel line edge coupler

Calculate the characteristic parameters of TEM mode microstrip coupler for different capacitive compensation

Need help, try Estimate for the approximate C's
