A planar sensor designed using the fourth Hilbert fractal curve iteration for solid material characterization at multiple frequencies is reported in this paper. The fractal curve is self-similar with space filling properties. The Hilbert fractal geom

This work proposes the use of the Particle Swarm Optimization method (PSO) to maximize the main beam of an intelligent, switched array of four Yagi-Uda antennas. The antenna feeds, amplitude and phase, are the PSO input variables, which not only maxi

This paper reviews the application of microwave signal-interference techniques to interferometers for frequency measurement and filters. The microwave interference takes place when the input-signal components pass through two different electrical pat

A planar dual-band circular antenna for a chemical wireless sensor network is described in this paper. Four antennas compose the wireless sensor package and one antenna is selected at a given time using an SP4T switch. This work describes the unit an

A novel Sierpinski carpet fractal dipole is here investigated. The new geometry of the fractals used in this study has slots suitably located, so that currents now flow near the edges of the squares which have been defined by the slots, and, as a res
