A novel printed loop antenna is designed introducing a C-shape portion to the left arm of the circular loop antenna. The proposed antenna gives frequency range from 3.5 to 6.20GHz. It is observed that lower frequency band depends on the C-shaped structure of circular loop antenna. However, the upper frequency band depends on the coupled tapered transmission line. Balun transformer of Z=50Ω to 80Ω...
In this paper a hybrid technique is used for determining the face from an image. Face detection is one of the tedious job to achieve with very high accuracy. In this paper we proposed a method that combines two techniques that is Orthogonal Laplacianface (OLPP) and Particle Swarm Optimization (PSO). The formula for the OLPP relies on the Locality Preserving Projection (LPP) formula, which aims at...
Development in field of broadband access technologies is on the rise due to increase in demand of high speed data services for portable devices. Despite recent advances in broadband wireless technologies, there remain a number of critical issues to be resolved. One of the major concerns is the implementation of compact antennas that can operate in a wide frequency band. Another important problem affecting...
