In this paper, UWB technology operating in broad frequency range of 3.1-10.6 GHz has shown great achievement for highspeed wireless communications. to satisfy the UWB system requirements, a band pass filter with a broad pass band width, low insertion loss, and high stop-band suppression. UWB band-pass filter (BPF) with wireless local area network (WLAN) notch at 5.8 GHz and 3-dB fractional band...

This paper presents a novel compact suspended double side millimeter bandpass filter (BPF) with wide stopband using Suspended Compact Microstrip Resonant Cell (SCMRC). For SCMRC exhibits slow-wave band-stop characteristics, two distributed SCMRC structures are designed to achieve wide stopband characteristic. By applying SCMRC structure and double side design, this novel BPF is size reduced. Ba...

This paper presents semicircular microstrip low pass filter with the sharp rejection and wide stop band. The proposed filter design is based on the calculations of filter parameters from traditional Hi-Lo impedance method and is available in the literature of microstrip filter. To further improve the design performance, high impedance lines are magnetically coupled, resulting an attenuation pol...

In this paper a new compact reconfigurable low pass/band stop filter using miniature omega resonator placed in small DGS the ground. The reconfiguration frequency response can be achieved with same topology and dimensions by changing just position of channel slot which connect to metallic ground without any other requirements. Several advantages obtained structure based on use one cell such as ...

This paper introduces a novel method named DEGL (Differential Evolution with global and local neighborhoods) regarding the design of two channel quadrature mirror filter with linear phase characteristics. To match the ideal system response characteristics, this improved variant of Differential Evolution technique is employed to optimize the values of the filter bank coefficients. The filter res...

In this work, we are interesting in the analysis and the design of an ultra wideband (UWB) band pass filter with improved upper stop band performances, using microstrip lines. The design of the UWB band pass filter is based on the use of stepped-impedance low pass filter and high pass filter; whereas the simulation of its frequency response ([S]) is done using MATPAR software and it is based on...
