In this letter, an antenna operating over the GSM band is proposed. Thanks to the use of a foam material as dielectric substrate, the prototype of this antenna is particularly light. It has a very low profile with overall dimensions equal to 0.31λ × …
In this paper a spline-shaped monopole radiator for utilization in Ultrawideband (UWB) Wireless Body Area Networks (WBANs) is presented. The antenna exhibits a good impedance matching and stable radiation patterns in the lower UWB band from 3.1 to …
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 letter, a spline-shaped ultrawideband (UWB) antenna enabling simultaneous operability over multiple mobile wireless standards-namely the DCS, PCS, UMTS, and ISM bands-is proposed. The antenna is expected to exhibit a good impedance matching …
The advantages of multiple-input multiple-output (MIMO) technology in ultrawideband (UWB) communication systems are investigated evaluating the channel capacity from measurements taken in indoor environments. The results suggest that in practical …
