This study presents a compact coplanar-waveguide (CPW) parallel-coupled bandpass filter (BPF) with good selectivity and stopband rejection. The inductive terminations are introduced to the conventional anti-parallel coupled-lines, and lumped-element J-inverters are employed, to achieve both size reduction and spurious suppression. Additionally, the inductive cross-coupling effect is introduced to obtain two transmission zeros to enhance the selectivity. Suitable equivalent-circuit model is also established as effective design tool. Specifically, this work demonstrates a compact cross-coupled fourth-order BPF in grounded-CPW configuration. Compared to the conventional filters, the proposed filters exhibit over 65% size reduction, improved selectivity, and wider stopbands up to four times the center frequency
