Abstract ▼ AI-Helper

A novel microstrip low-pass filter is presented to achieve an ultra-wide stopband with 11 harmonic suppression and very sharp skirt characteristics. The filter is composed of a modified U-shaped resonator (which creates two fully adjustable transmission zeroes), a T-shaped resonator (which determines a cut-off frequency), and four radial stubs (which provide a wider stopband). The operating mechanism of the filter is investigated based on a proposed equivalent-circuit model, and the role of each section of the proposed filter in creating null points is theoretically discussed in detail. The presented filter with 3 dB cut-off frequency ($f_c=2.35GHz$) has been fabricated and measured. Results show that a relative stopband bandwidth of 164% (referred to as a 22 dB suppression) is obtained while achieving a high figure-of-merit of 15,221.

대상 데이터

A compact LPF with sharp roll-off and wide stopband bandwidth is proposed and implemented. The filter is composed of a U-shaped fully adjustable resonator, four radial stubs, and a T-shaped resonator. The first two sections contribute to the creation of an ultra-wide stopband, while the T-shaped resonator provides a fully adjustable cut-off frequency with a very sharp roll-off.
