Development of ultrathin metasurface and partially reflective surface antennas for space applications
La industria espacial ha estado siempre muy interesada en la evolución de las antenas que se integran en los satélites. Se buscan soluciones que además de ser ligeras y compactas, tengan un coste reducido. De esta forma ... -
Dual circularly polarized broadside beam metasurface antenna
This paper presents the design of a modulated metasurface (MTS) antenna capable to provide both righthand (RH) and left-hand (LH) circularly polarized (CP) boresight radiation at Ku-band (13.5 GHz). This antenna is based ... -
Experimental validation of a Ku-band dual circularly polarized metasurface antenna
The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ... -
Low profile THz periodic leaky-wave antenna
In this work, a 0.566THz flat leaky-wave antenna, consisting of a central λ0/2 slot surrounded by straight parallel wedge corrugations, is numerically and experimentally analyzed. Simulations show a moderately high gain ... -
Research on metamaterials for antenna applications
During the last 20 years a lot of attention has been paid to apply Electromagnetic Band Gap (EBG) technology in different frequency ranges, from microwaves to optics. EBG technology is based on the use of periodic structures ... -
A slow light fishnet-like absorber in the millimeter-wave range
A novel route to achieve a narrowband free-space electromagnetic absorber in any range of the spectrum based on stacked subwavelength hole arrays is proposed. The absorption is obtained by means of a slow light mode inside ... -
Terahertz carpet cloak based on a ring resonator metasurface
In this work we present the concept and design of an ultrathin (λ/22) terahertz (THz) unidirectional carpet cloak based on the local phase compensation approach enabled by gradient metasurfaces. A triangular surface bump ...
