Miniaturized Dual-Band Dual-Mode TM-Mode Dielectric Filter in Planar Configuration

Dual-Band Evanescent-Mode Substrate Integrated Waveguide Band-pass Filter for WLAN Applications

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...

Novel Quadruple-mode, Dual-mode and Dual-band Dielectric Resonator Filters and Multiplexers

Fractal 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 ...

Design 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 ...

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...
