| Abstract: | Rapid development of wireless communication present extraordinary demand for RF microwave filters with high selectivity and small size.A new type of microwave bandpass filter using microstrip open-loop resonators is proposed,which exhibit a pair of attenuation poles.A practical design technique for this kind of filter is introduced,including formulas and accurate calculation.A design example of a eight-pole filter with a fractional bandwidth of 9.534% at 1123 MHz is described.Theoretical and experimental re... |
