In this paper an antenna array for imaging applications is presented. A two-step design process is used. In the first step, a wideband printed monopole antenna to be employed as the array element is synthesized by means of a Particle Swarm …
In this letter, a dual-band fractal monopole antenna suitable for Long Term Evolution (LTE) standard is proposed. The antenna geometry is based on a perturbed planar Sierpinski fractal shape, whose geometrical descriptors are determined by means of a …
In this paper, an approach for the synthesis of Ultra-Wideband (UWB) antennas with a notched frequency band is presented. It exploits the effectiveness of a representation based on spline curves to obtain the wideband behavior and the simplicity of …
The recent development of many new ultra-wideband (UWB) array technologies has created a demand for antenna elements that can effectively operate over similar bandwidths. For example, the polyfractal [1] and RPS [2] topologies are capable of …
In this paper, we propose a novel approach to automatically plan video cameras positioning in indoor environments for surveillance applications. In order to ensure maximum coverage of the observed scene, we have implemented an ad-hoc tool based on …
In this paper, an approach for the synthesis of antenna systems suitable for UWB communication applications has been presented. The final antenna geometry is obtained by means of a PSO aimed at fitting a set of time domain requirements. Such …
Synthesis of ultrawideband (UWB) antennas by means of a particle swarm optimizer (PSO)-driven spline-based shaping approach is described. In order to devise a reliable and effective solution, such a topic is analyzed according to different …
This letter presents the design of a planar antenna for ultrawideband (UWB) applications with a bandwidth of 5.5 GHz over 3.7 to 9.2 GHz and return loss values lower than -10 dB. The antenna geometry is described in terms of a spline-based …
