The main problem in designing a multiband bandpass filter (BPF) is making each passband
response highly independent, where each bandwidth of multiband BPF can be controlled …

A compact dual wide-band multiple-input-multiple-output (MIMO) radiator is presented in this
article. The MIMO radiator is developed on a 1.5 mm thick FR-4 substrate. The proposed …

Integration of high-sensitivity sensors with multiple sensing performance for the
environmental detection of permittivity (ε r), conductivity (σ), and the refractive index (n) is …

A stepped impedance resonator (SIR) is suitable for designing a dual-band bandpass filter
(BPF) that can be adjusted to reject spurious bands. A BPF is proposed using an SIR T …

In this paper, circular-shaped microstrip antenna was simulated, fabricated, and measured
accordingly. As the novelty, to enhance bandwidth and reduce antenna size, beleved half …

Portable wireless communication systems are increasingly in demand in small sizes for
human convenience. In wireless communication systems, the performance, size, and unit …

This paper exhibits the design and implementation of a compact dual-band bandpass filter
on paper substrate. The proposed filter which works on the principle of signal interference …

Complementary Split Ring Resonators were used embedded in a substrate integrated
waveguide to generate passband charateristics in X-Band. Based on a parameter study with …

A CPW (coplanar waveguide) bandpass filter based on spiral-shaped DGSs (defected
ground structures) which can be used in the 5G band is proposed. Two pairs of face-to-face …

A band-pass filter (BPF) is an essential part of a wireless communication system as it
functions to reduce interference and noise. Many structures have been proposed to achieve …
