Artificial neural network design of stub microstrip band-pass filters

In this paper an Artificial neural network (ANN) design technique for a Stub Microstrip Band-pass filter is presented. Essential dimensions of the microstrip filter layout are used to get the relationship in the inputoutputs of ANN model. This paper presents the design and analysis of Stub Microstrip Band-pass Filter at midband frequency 1.8 GHz which gives improved bandwidth and minimum insert...

High-performance variable band-pass/band-stop state-space digital filters using Gramian-preserving frequency transformation

Dimensional Synthesis for Wide-band Band- Pass Filters with Quarter-wavelength Res- Onators

This paper presents a dimensional synthesis method for designing wide-band quarter-wavelength resonator bandpass filters. In this synthesis method, an alternative lowpass prototype filter and the edge frequency mapping method are proposed and applied. The improved Kand J-inverter model with the exponent-weighted turns ratio is also proposed in order to incorporate the frequency dependence of in...

Design of a Micro strip Quad-Band Band pass Filter for LTE Using Stub Loaded Resonators

A Quad-band bandpass filter for wireless RF devices is presented. The circuit is capable of serving multiple FDD and TDD bands of the 4G LTE standard. A microstrip transmission line is used to feed stepped impedance resonators for providing four bands in LTE spectrum. The proposed filter is simulated using IE3D simulator. The centre frequency and bandwidth of each passband can be controlled by ...
