A Novel Microstrip Dual-Mode Band-pass Filter For second Harmonic Suppression
Engineering and Technology Journal,
2010, Volume 28, Issue 11, Pages 2206-2211
AbstractA novel design scheme has been introduced in this paper to suppress 2nd harmonic
from response of band-pass filter (BPF) which appears at about . The filter is
composed of perturbed, square-ring resonator and open end stup length where
wavelength for harmonic located on the output feeder port work as Band Stop
Filter. The harmonic suppression of the BPF may be realized by choosing a
proper length of the open stup which is equal to . The BPF investigated is for more
frequencies such as (GPS, ISM, RFID, and GSM).
The performance of BPFs with open stup structures has been analyzed using
method of moments (MoM) based software microwave office, which is widely
adopted in microwave research and industry.
