Compact Multilayer Bandpass Filter with Modified Hairpin Resonators
نویسنده
چکیده
Compact selective bandpass filter, based on the Rhodes approximation, is proposed using the novel modified hairpin resonators realized on a double-sided microstrip. The equivalence is presented between the hairpin resonator realized on a singlesided microstrip and the modified hairpin resonator realized on a double-sided microstrip. The footprint area of the filter is reduced by 50% with the multilayer realization. The proposed design methodology is exemplified by a fourth-order multilayer bandpass filter, which is fabricated and measured. The simulated and measured results are in agreement.

This paper presents a compact bandpass filter with stopband and high attenuation by using multilayer folded broadside-coupled quarter-wavelength stripline resonators in a low-temperature co-fired ceramic (LTCC) substrate. The proposed bandpass filter centered at 1.1 GHz with a fractional bandwith of 4.5 % shows the first spurious frequency at 3.8 times the center frequency. In comparison to the...
