En este proyecto se presenta el diseño y simulación de una agrupación de antenas multihaz ultra-wideband. La agrupación está compuesta por cuatro monopolos UWB, diseñados para trabajar a frecuencias entre 4.5 GHz y 10 GHz. ...

We show that specially designed two-dimensional arrangements of full elastic cylinders embedded in a nonviscous fluid or gas define ( in the homogenization limit) a new class of acoustic metamaterials characterized by a ...

This communication demonstrates experimentally the improvement in axial ratio performance when a slot is combined with a set of three parasitic dipoles instead of one. The analysis is performed in the context of slotted-waveguide ...

[EN] The main purpose of this project is the improvement of an antenna already manufactured. This radiant system works for applications in the 2.45GHz frequency range and broadcasts with a circular polarization. The antenna ...

[EN] This letter presents an 8 x 8 dual-band shared-aperture array antenna operating in K-(19.5-21.5 GHz) and Ka-band (29-31 GHz) using gap waveguide technology. Radiating elements consist of circular apertures located on ...

[EN] Millimeter-wave communication systems require many innovative antennas adapted for future application scenarios such as the upcoming 5G cellular networks. Due to the strong path loss in free space at the millimeter-wave ...
