CAD‐oriented analytic formulas are presented for calculating the quasistatic parameters of the conductor‐backed asymmetric coplanar waveguide (ACPW), the ACPW with upper shielding, and the conductor‐backed ACPW with upper shielding using conformal mapping techniques. The effect of the presence of the upper shielding and the conductor‐backing on the quasistatic TEM parameters is discussed. It is also presented that the expressions derived in this work can be used for calculating the quasistatic parameters of various symmetric and asymmetric CPWs. ©1999 John Wiley & Sons, Inc.
