In this paper, a compact parallel coupled microstrip band-pass filter (BPF) is used to design a wideband third order of the Tschebyshev elements for an unlicensed WiMAX technology. Some techniques based on the parametrical study are proposed to obtain the desired 10 % operating bandwidth filter response. The new filter is implemented on Arlon AR 1000 substrate having a relative permittivity of ...

Planar band pass filters (BPF) with low insertion loss, compact size, high selectivity, wider bandwidth and good stop band rejection are required for the next generation mobile and satellite communication systems. In the case of the planar filter solution, electrical performance with regard to both out-of-band rejection and in-band transmission losses, as well as cost, reliability and dimension...

In this paper, a band-pass filter (BPF) based on split-ring resonator (SRR) using 3-D printing technique for C-band applications is introduced. The proposed designed to operate at frequency of 3.9 GHz. An innovative the substrate with size 24 x 1.1 mm3 PLA dielectric material implemented. copper sheet thickness 0.1 mm printed upper and lower faces substrate. First, SRR band stop (BSF) introduce...

Ultra-wide band (UWB) is a very attractive technology for innovative in-car wireless communications requiring high data rates. A designated antenna, which presents a reflection coefficient (S11) matched band comparable to the Band Pass Filters (BPF) normally required at the transducers, plays a positive contribution in this in-car application and was validated for the scenario. The inherited BP...

A band-pass filter is a wireless component that transmits frequencies within certain range and attenuates outside range. Band-pass (BPF) has been used as core for an Radio Frequency (RF) communication system. BPF generally designed based on transmission line resonators. Therefore, miniaturization of these components important. In this study, triangle-shaped with meander-line resonator complemen...

brain-computer interfaces (bci) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. these systems do not use normal neuromuscular output pathways. actually, the principal goal of bci systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic la...

A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...

A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...
