A Novel coplanar waveguide (CPW) fed Ultra Wideband (UWB) slot antenna is presented in this paper. The antenna consist a rectangular slot with cross type structure as a tuning stub with CPW feed. The CPW feed is designed for 50 Ω impedance. The physical size of the proposed antenna is 19 mm(L)×20mm(W)×1.6mm(T) and the electrical size is(More)
Mobile Ad hoc Network (MANET) is well known for its limited transmission range of wireless network interface. Hence, multiple hops (multi-hops) may be needed for exchanging the information from one node to another across the network without any base stations or routers. In MANETs, as there is no hierarchy among nodes, every node is responsible for(More)
Design and analysis of a new coplanar waveguide (CPW) fed ultra wideband (UWB) slot antenna is presented in this paper. The proposed antenna is simple, compact and low cost. The overall dimension of the antenna is 28&#x00D7;21&#x00D7;1.6 mm<sup>3</sup> and fed by 50&#x2126; coplanar waveguide. The parametric analysis of the antenna is done by using MoM(More)
A Quad-band bandpass filter for wireless RF devices is presented. The circuit is capable of serving multiple FDD and TDD bands of the 4G LTE standard. A microstrip transmission line is used to feed stepped impedance resonators for providing four bands in LTE spectrum. The proposed filter is simulated using IE3D simulator. The centre frequency and bandwidth(More)
This paper proposes new real time color recognition features, i.e., extracting primary colors for the purpose of vision-based human–computer interaction. Vision-based human–computer interaction could be achieved by analyzing segmented primary color regions. However, one of the challenges of color-based target tracking is that color distributions would(More)
In this paper, a design and analysis of compact coplanar waveguide (CPW) fed wideband slot antenna is presented. The proposed antenna has simple structure consisting of rectangular slot, triangular feeding structure at the anterior portion of the feed. The overall dimension of the antenna comes around only 21 mmtimes20 mmtimes1.6 mm and fed by 50 Omega(More)
Acknowledgments I would like to thank Professor Risto Miikkulainen for being unbelievably patient and encouraging during the creation of this thesis. I want to thank all my friends who put up with me saying "I'm going nish it soon ... really I am ..." thousands of times. In the past several years, evolutionary algorithms such as simulated annealing and the(More)
