The release from the U.S. Federal Communication Commission (FCC) of the unlicensed use of the Ultra-Wide-Band (UWB) frequency range of 3.1-10.6 GHz, fed the interest for developing communication systems to be used on applications requiring high data rate transmission. The complete success and spreading of these novel applications requires inexpensive and reliable UWB communication systems and devices. The set of passive components included in these systems is definitely a key point on their full development. To this end, many efforts have been done by both the academic and industrial sectors, focusing their research activities on the development of UWB passive components.
