A new de-embedding technique for the analysis of printed circuits and antennas based on the Characteristic Basis Function Method

In this paper we present a new de-embedding algorithm for an efficient evaluation of the S-parameter for printed microwave circuits or antennas. The proposed technique is based on the Characteristic Basis Function Method (CBFM) with exponential type of Characteristic Basis Functions (CBFs) which can be exploited in order to mitigate the low frequency problems associated with the conventional de-embedding techniques. A numerical example that demonstrates the numerical accuracy and efficiency of the proposed method is included.
