“…Planar microstrip LPF has attracted great attention due to its advantages of small size, low‐cost and easy of fabrication. To date, several structures have been reported to obtain high‐performance lowpass filters 1‐14 . In Reference 3, a microstrip low‐pass filter using a stepped impedance hairpin resonator with a pair of coupled stepped impedance resonators (SIRs) inside is presented.…”

“…In Reference 11, a microstrip LPF with sharp roll‐off and wide stopband consisting of radial split ring resonator loaded by folded polygene patches is proposed. In References 12 and 13, defected ground structures are adapted for performance improvement. In Reference 14, a microstrip LPF uses complementary rectangle split ring defected microstrip structure to improve the stopband and suppress the harmonic response.…”

A high‐performance microstrip lowpass filter with coplanar waveguide as the ports is proposed and analyzed. By cascading asymmetric hairpin resonators, a compact elliptic function low‐pass filter with wide stop band was realized. The filter was optimized using aggressive space mapping algorithm, and finally a filter with a cut‐off frequency of 11.8 GHz was obtained. Stop bandwidth with attenuation level better than −27 dB extends from 15.6 to 36 GHz. Also, the maximum insertion loss in the passband is 0.9 dB and the return loss is better than −22 dB. The filter is manufactured on the silicon wafer using micro‐electromechanical systems process, and the measured results in good agreement with the simulation results.

In this article, a compact microstrip low-pass filter (LPF) with low in-band insertion loss and a wide attenuation band is recommended. The structure is modeled using two rectangular-shaped open resonators (ORs) loaded with multiple sections of the interdigital capacitor. The proposed LPF has a cut-off frequency of 1.5 GHz, a passband insertion loss of 0.35 dB, and an electrical circuit size of 0.02 λ g 2. In the ground plane, two dissimilar defected ground structures (DGSs) are introduced to generate additional attenuation poles for enriching the stopband performance of the LPF. The harmonics suppression is achieved up to 15 GHz with tenth harmonic suppression and relative stopband rejection of almost 165%. The EM simulated results show a well-matched behavior with the experimental ones. The proposed LPF can be used for global positioning systems (1500 MHz), telecommunications (1600 MHz), and audio broadcasting (1400 MHz) applications.
