Properties of microstrip filter with elliptic-fractal pattern.
We described the properties of microstrip band gap filter with elliptic-fractal pattern from 40 Hz to 20 GHz. It used the characteristic of the fractal and elliptic pattern to improve the performance of microstrip band gap filter. The center frequencies of gaps of the filter were about 5.5 and 15 GHz, and the band stop bandwidth of the filter can be increased by increasing the numbers of the ce...
متن کاملInvestigations on an H-fractal Wideband Microstrip Filter with Multi-passbands and a Tuned Notch Band
This paper investigates an H-fractal wideband microstrip filter with multi-passbands and a tuned notch band for wireless communication frequencies. The four different filter configurations explored are: symmetric with zero offset, symmetric with nonzero offset, asymmetric with zero offset, and asymmetric with nonzero offset. The effect of H-fractal iterations, fractal scaling parameters, and st...
متن کاملDesign of Microstrip Band Pass Fractal Filter for Suppression of Spurious Band
In this paper, the design and subsequent fabrication of a hairpin-line band pass filter has been proposed. This filter exhibits periodic frequency response. By proper design, the spurious bands are being suppressed significantly through the implementation of Koch fractal on the microstrip coupled line.
متن کاملDesign and Analysis of Stepped Impedance Microstrip Fractal Low Pass Filter
Most communication system contains an RF front end which performs signal processing with RF filters. Micro strip filters are a low cost means of doing this. This paper describes the design of low cost and low insertion loss microstrip stepped impedance Fractal low pass filter (LPF) by using microstrip layout which works at 0.4 GHz for permittivity 4.7 value with a substrate thickness 1.6 mm wit...
متن کاملCompact Microstrip Bandpass Filter with Multispurious Suppression
A compact microstrip bandpass filter (BPF) with multispurious suppression is presented. The filter consists of two coupled half-wavelength stepped impedance resonators (SIRs) and tapped input/output (I/O) lines. With tuning the impedance ratio (K) and length ratio (α) of SIRs, a very wide stopband can be easily achieved. The filter is designed at 2.4 GHz (f0) with a wide stopband to 20GHz (8.16...
