A Novel Microstrip Dual-band Bandpass Filter Using Dual-mode Square Patch Resonators
Dual-mode square patch resonator is well known in the design of a single band quasi-elliptic bandpass filter response. Here, the dual-mode square patch resonator is employed to achieve a dualband bandpass filter. A 6 pole dual-band bandpass filter response with 3 poles at each passband will be presented. The dual-band filter also exhibits a transmission zero between the two passbands. A detaile...
متن کاملMicrostrip Dual-Band Bandpass Filter Using U-Shaped Resonators
Coupled resonators are widely used in the design of filters with dual-passband responses. In this paper, we present a dual-band bandpass filter using only couplings between adjacent resonators without cross-couplings. The dual-band bandpass filter with centre frequencies of 1747MHz and 1879MHz respectively is designed and fabricated using microstrip U-shaped resonators. Using the coupled resona...
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 ...
متن کاملDesign of a Compact Dual-mode Dual-band Microstrip Bandpass Filter Based on Semi-fractal CSRR
Various complementary split ring resonators (CSRRs) are used as defected ground structures (DGSs) in the bandpass filter (BPF) design for different communication applications. In this paper, a hybrid CSRR has been introduced as a DGS in the ground plane of a dual-mode microstrip BPF to produce a new compact filter with dual band response. The proposed CSRR structure is essentially based on the ...
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...
