Design of miniaturized bandpass filters using quasi-lumped Multilayer Resonators
A novel design procedure for a compact multilayer bandpass filter is proposed and examined. The filter is realized using quasi-lumped multilayer resonators. Based on the orientation of these coupled-resonator pairs, a second-order bandpass filter is realized with transmission zeros. In order to achieve a low external quality factor, i.e., a wider filter bandwidth, different types of feeder real...
متن کاملRobust optimal granulometric bandpass filters
A granulometric bandpass "lter (GBF) passes certain size bands in a binary image. There exists an analytic formulation for the optimization of GBFs in terms of the granulometric size density of a random set. This size density plays the role of the power spectral density for optimization of linear "lters. An optimal "lter depends on the parameters governing the distribution of the random set. In...
متن کاملElectronically scanned RF-to-bits beam aperture arrays using 2-D IIR spatially bandpass digital filters
A beamforming system based on two-dimensional (2-D) spatially bandpass infinite impulse response (IIR) plane wave filtering is presented in a multi-dimensional signal processing perspective and the implementation details are discussed. Real-time implementation of such beamforming systems requires modeling of computational electromagnetics for the antennas, radio frequency (RF) analog design asp...
متن کاملCircular Waveguide TM11-Mode Resonators and Their Application to Polarization-Preserving Bandpass and Quasi-Highpass Filters
Circular waveguide filters with improved performance are presented. They are based on TM11-mode resonators which permit the filter to be smaller than standard TE11-mode filters, preserve all polarizations due to rotational symmetry, and are flexible with respect to the design of bandpass or highpass filters. In order to demonstrate their advantages, they are compared to a standard TE11-mode des...
متن کاملMicrostrip Interdigital Bandpass Filters: Design analysis
Conventionalmicrostriplowpass and bandpass filters such as stepped-impedance filters, open-stub filters, semilumped element filters, endand parallel-coupled half-wavelength resonator filters, hairpin-line filters, interdigital and combline filters, pseudocombline filters, and stub-line filters are widely used in many RF/microwave applications. Modern RF and microwave communication systems, spec...
