Therefore a phase shift is occurring in the capacitor, the amount of phase shift between voltage and current is +90° for a purely capacitive circuit, with the current LEADING the voltage. The opposite phase shift to an inductive circuit.
In this case, the phase shift starts at +90°, and the filter is a high-pass. Beyond the cutoff frequency, we eventually settle to 0°. So we see a series capacitor will always contribute between +90° and 0° phase shift. With this information at our disposal, we can apply an RC model to any circuit we wish.
Since voltage and current no longer rise and fall together, a "PHASE SHIFT" is occurring in the circuit. Capacitance has the property of delaying changes in voltage as described in Module 4.3. That is, the applied voltage reaches steady state only after a time dictated by the time constant.
The phase relationships created by inductors and capacitors are described using the words leading and lagging. In a DC system, a capacitor’s voltage reaches the maximum value after its current has reached the maximum value; in an AC system, we say that the capacitor creates a situation in which voltage lags current.
A shunt capacitor will cause between 0° and -90° phase shift on a resistive load. It’s important to be aware of the attenuation too, of course. A similar look at a series capacitor (for example, an AC-coupling cap) shows the typical effect for that configuration. Figure 3. Series capacitor circuit... Figure 4. ... And its bode plot
• Phase Shift in Common AC Components. In purely resistive circuits, the current and voltage both change in the same way, and at the same time, as described in Module 4.1. This relationship is true, whether the applied voltage is direct or alternating.

Phase Difference and Phase Shift
Phase shifting is basically about time delaying the base frequency. Your 3.58MHz frequency will have a period of 279.33nS, thus delaying the input signal by multiples of 69.83nS would give the desired 90, 180, and 270 o of phase shift.
