The development of UWB technology is very helpful in supporting high-speed data access. offers a solution for large capacity wide bandwidth. frequency range systems between 3.1–10.6GHz will cause interference to wireless communication via local area networks (WLANs) IEEE 802.11a operating at 5.15–5.35GHz and 5.725–5.825GHz. This research aims obtain design rectangular printed monopole patch mic...

In this paper, a unit cell of single-negative metamaterial structure loaded with meander line and defected ground (DGS) is investigated as the principle radiating element an antenna. The antenna causes even or odd mode resonances similar to depending on orientation microstrip feed used excite cell. However, which gives low-frequency resonance considered here. then parallel split bearing side co...

This letter proposes a multi-passband half-mode substrate integrated waveguide (HMSIW) filter based on the theory of odd and even mode analysis. The adopts triangular HMSIW cavity cut along diagonal rectangle. By etching two dual-mode resonators, resonant resonator is coupled with odd-even to achieve multiple passbands. defected ground structure (DGS) can reduce resonance frequency without incr...

The performance of a high pass filter (HPF) and a band pass filter (BPF) with and without defected ground structure (DGS) was analyzed in this specific work. The Defected ground structure includes rectangular and circular etched shapes in ground plane. Calculation and comparison of the response of both filters was done separately. Parameters of the proposed configuration were calculated at the ...

This paper presents analysis and design of a compact ultra wide band (UWB) filter using three parallel folded coupled lines in a defected ground structure in multi-layer structure. Defected ground has been incorporated under the coupled lines of the filter to improve the coupling over a wide bandwidth. The closed form expressions for even and odd mode impedances for the coupled lines with defec...
