Compact and selective lowpass filter with spurious suppression

A novel coplanar-type compact and selective lowpass filter is proposed. It consists of a simple high-impedance transmission line loaded with capacitors. Spurs are completely suppressed, with an attenuation larger than 20 dB outside the passband. The return loss is greater than 16 dB in the passband and the attenuation slope is more than 500 dB/decade for a 0.6 λ-long filter.
