According to Federal Communication Commission (FCC) rules, the 3.1-10.6GHz band is allocated to the Ultra-Wide Band (UWB) applications. Due to the overlap of the currently allocated UWB frequency band with the communication systems such as Wireless Local Area Network (WLAN) bands in the 2.4GHz(2.4-2.484GHz), 5.2GHz (5.15-5.35GHz) and 5.8GHz(5.725-5.825GHz) bands and the World Interoperability for Microwave Access (WiMAX) system bands 2.5GHz(2.5-2.69GHz), 3.5GHz (3.4-3.69GHz) and 5.8GHz (5.25-5.825GHz). Therefore, an unwanted intrusion will be expected between these frequencies, now-a-days many systems operate across several frequency bands, requiring a band-notched or band-rejected function.
