Microwave band pass filters play an important function in radio frequency for suppressing
out-of-band emissions that are necessary in today's wireless communication. The study …

A narrowband dual-band bandpass filter (BPF) with independently tunable passbands is
presented through a systematic design approach. A size-efficient coupling system is …

This paper presents a very efficient design procedure for a high-performance microstrip
lowpass filter (LPF). Unlike many other sophisticated design methodologies of microstrip …

In this paper, a compact diamond-shaped dual-band bandpass filter with seven transmission
zeros in the stopband and two poles in each passband is designed, analyzed, and …

A novel configuration of a dual-band bandpass filter (BPF) working as a harmonic attenuator
is introduced and fabricated. The proposed filter operates at 3 GHz, for UHF and SHF …

In this paper, a new coupler is designed using proposed resonator cell and meandered
lines. The proposed coupler correctly works at 1 GHz operating frequency. The compact size …

This article presents the design and analysis of a compact dual‐band bandpass filter
employing coupled lines and open circuit stub. The filter frequency response contains two …

This article proposes a new branch-line coupler design using two trapezoid-shaped
resonators, applied in side and center. The standard 35 and 50 Ohms λ/4 transmission lines …

In this work, a dual‐mode substrate integrated coaxial line (SICL) bandpass filter supporting
single‐band and dual‐band operation for widely spaced passbands located in X and K …

In this paper, metamaterial loading on loop and open loop microstrip filters is investigated
where both rectangular loop and open loop structures are considered. Spiral resonators are …
