Planar Microstrip Bandpass Filter with Wide Dual Bands Using Parallel-coupled Lines and Stepped Impedance Resonators
A dual-band bandpass filter with wide and highly attenuated stopbands is designed using parallel coupled microstrip line (PCML) and stepped-impedance-resonators (SIRs). The proposed filter is composed of a pair of highly coupled PCML-SIR structure and a central resonator using a low impedance rectangular microstrip. Initially, the wide dual-band performance is achieved by creating a transmissio...
متن کاملMicrowave Dual-Band Bandpass Filter using L-shaped Stepped Impedance Resonators
This work demonstrates a microwave dual band bandpass filter using two L–shaped stepped impedance resonators (SIRs) and a coupled feed structure. The coupled feed structure can be a single sided or a double sided structure. Two sets of physical parameters are used to control the coupling coefficient and external quality factor. Thus, the specification, such as the central frequencies and the ba...
متن کاملTunable Active Dual-Band Bandpass Filter Design Using MMIC Technology
Abstract— The inductor-less designing of monolithic tunable active dual-band bandpass filter is presented in this study. Biasing voltages signify main role. They can control the center frequency and quality factor. Using four biasing voltages and cascading two similar filters leads to dual-band bandpass filter. By keeping the gain constant, the center frequency shift is 200 MHz. Regardless cons...
متن کاملA Simple Asymmetrical Step-Impedance Resonator Dual-Band Bandpass Filter
Designing of dual-band bandpass filters has become wide spreading to support wireless communication system standards including WLANs [1-6]. Although they have presented new structures for reducing size by using a quarter wavelength structure in [1-3], meandered resonator to increase coupling value for high selectivity [4-5], and interdigital capacitors between resonators for high selectivity, t...
متن کاملFractal Bandpass Filter Using Y-shaped Dual-Mode Resonator for C-Band Receiver (Research Note)
In this study, a fractal, Y-shaped dual-mode resonator bandpass filter (BPF) with input-output cross-coupling is introduced. A parallel-coupling feed structure with a cross coupling has been used to generate two transmission zeroes (TZs) near the lower and upper cutoff frequency that can effectively improve the passband edge selectivity. Also, a fractal shaped based on conventional diamond and ...
