Ultra-wideband antenna with band notch for rejecting bands. Rectangular slots are introduced on an arborescent patch to get UWB, coverage from 3.1–10.6 GHz. The structure is fancied FR4 the substrate a size of 24 mm×24 mm×1.6 mm, located at 4.7 GHz generated by adding rectangular slot this microstrip simulated computer simulation technology, and manufactured results show wireless communication,...

A second order voltage mode tunable universal filter is presented. The voltage mode filter is based on dual output second generation current controlled current conveyor (DOCCCII). The filter is capable of realizing high pass (HP), low pass (LP), band pass (BP), notch pass (NP) and all pass (AP) responses in voltage mode (VM). The filter employs only two capacitors and hence enjoys minimum compo...

This paper presents a multiple exchange algorithm for designing linear phase equiripple FIR notch "lters. The algorithm is "rst discussed for designing a single notch "lter. Compared with conventional linear programming methods, the design speed can be improved signi"cantly. Then, two modi"ed algorithms are developed to reduce the ripple in the low-frequency passband because the energy of biome...

High data rate transmission is the need of modern wireless communication systems. Broadcast antennas are in demand as EM waves are transmitted at high frequency for high data rate transmission. Low profile, light weight, inexpensive, compact printed antennas are well suited for broadcasting for their ability to operate in broad frequency range. Printed microstrip antenna (Patch antenna) is used...

A novel perturbation approach using additional metalized via-holes for implementation of the dual-band or wide-band dual-mode substrate integrated waveguide (SIW) filters is proposed in this paper. The independent perturbation on the first resonant mode TE101 can be constructed by applying the proposed perturbation approach, whereas the second resonant mode TE102 is not affected. Thus, new kind...
