Abstract

A compact microstrip lowpass filter with harmonic suppression exhibits ultra-wideband rejection. It is based on triangular patch resonators and a butterfly patch resonator with two 120 degree radial "wing" patches. A filter of this design with a 3 dB cutoff frequency at 1.78 GHz achieves a harmonic suppression bandwidth of 158 percent, enabling it to suppress the twelfth harmonic response. Its small size of 14.5 mm X 18 mm corresponds to 0.133 λg x 0.165 λg, where λg is the guided wavelength at 1.78 GHz. [ABSTRACT FROM AUTHOR]
