Compact Triple-Band Bandstop Filters Using Embedded Capacitors
By
Progress In Electromagnetics Research Letters, Vol. 63, 15-21, 2016
Abstract
This paper presents a design of a compact triple-band bandstop filter (BSF) using embedded capacitors. The presented BSF is useful to suppress the signal frequencies 2.2 GHz, 5.53 GHz and 4.15 GHz from the WLAN and UWB band with attenuation level 33.5 dB, 27.6 dB and 24.9 dB, respectively. The quality factors of the three bands are 5.21, 31.92 and 79.0, respectively. The simulated and measured results are presented to validate the concept. Such BSFs could find application in modern communication systems to suppress the potential interference of the unwanted frequencies from the WLAN and UWB band.
