September 2009 [Components] DGS-Based Resonators Form Lowpass Filters Microstrip filters formed with defected ground structures (DGSs) offer high performance levels at microwave and millimeter-wave frequencies. By building upon that technology, it has been possible to develop a novel symmetrical split ring resonator (SSRR) DGS that has been used to fabricate lowpass microwave filters with wide rejection bands. Several filters were simulated and fabricated based on SSRR DGS units, with good agreement between... January 2009 [Components] Build Lowpass Filters With Elliptic DGS Defected-ground-structure (DGS) circuit elements show great promise for reducing the size of circuit designs at microwave and millimeter-wave frequencies. 1 For active circuits, such as amplifiers, and passive component designs, such as couplers, DGS elements provide circuits with excellent performance at high frequencies. In particular, miniature filter designs can benefit from the use of DGS circuit elements.1,2 To demonstrate the... September 2008 [Components] Uneven DGS Cells Construct Compact LPF Defected-ground-structure (DGS) cells can serve as effective building blocks for high-performance, high-frequency filters. Microstrip filters are widely used in microwave and millimeterwave systems and, in particular, low-pass filters (LPFs) are essential components in modern communications systems.1 The increasingly challenging requirements of such systems calls for LPFs with increasingly improved performance for in-band and out-of-band ... |
