“…By including the input and output matching impedance, the size of the proposed LPF is about 19.83 mm × 8.64 mm. The proposed filter in comparison to other filters in [3] to [8] has notable reduction in the transition band and stop bandwidth. Additionally, a wider stopband and sufficient response in the passband region is achieved.…”

A compact microstrip lowpass filter (LPF) with an elliptic function response is proposed. A high equivalent capacitance and inductance between the structures of the resonator result in the sharp transition band of 0.04 GHz from 4 GHz to 4.04 GHz with an attenuation level of -3 dB and -20 dB, respectively. To improve the LPF rejection band, multiple open stubs are connected to the proposed resonator. A filter with a 3-dB cut-off frequency at 4 GHz is designed

“…Thus the proposed meander-like low-pass filter is much more compact with low insertion loss than the other two low-pass filters. The meander-like low-pass filter has a high achievable roll-off rate of 246.7 dB/GHz with an achievable relative stopband bandwidth of 0.883 [12] and could be advantageous where a much deeper out-of-band rejection is required.…”

“…To develop the stop-band of the low-pass filter in [11], improved hairpin resonators were adopted; nonetheless the transition-band is slow. Multi-layer LPFs such as defected ground structure (DGS) [12][13][14][15][16][17][18][19], do not have a wide stop-band and sharp transition-band, moreover these filters suffer from complex structure.…”
