Artificial Magnetic Conductor Frame to Improve Impedance Matching and Radiation Symmetry in 22 Array for 6G Applications
Edoardo Giusti, Krishan Kumar Tiwari, C. J. Reddy +3
An Artificial Magnetic Conductor (AMC) frame capable of improving the impedance matching of a 22 array for 6G applications without degrading isolation performance is presen…
A Circuit-based Model for the Interpretation of Perfect Metamaterial Absorbers
Filippo Costa, Simone Genovesi, Agostino Monorchio +1
A popular absorbing structure, often referred to as Perfect Metamaterial Absorber, comprising metallic periodic pattern over a thin low-loss grounded substrate is studied by resort…
Analysis and Design of Ultra Thin Electromagnetic Absorbers Comprising Resistively Loaded High Impedance Surfaces
Filippo Costa, Agostino Monorchio, Giuliano Manara
High-Impedance Surfaces (HIS) comprising lossy Frequency Selective Surfaces (FSS) are employed to design thin electromagnetic absorbers. The structure, despite its typical resonant…
On the Bandwidth of High-Impedance Frequency Selective Surfaces
Filippo Costa, Simone Genovesi, Agostino Monorchio
In this letter, the bandwidth of high-impedance surfaces (HISs) is discussed by an equivalent circuit approach. Even if these surfaces have been employed for almost 10 years, it is…
An Active High Impedance Surface for Low Profile Tunable and Steerable Antennas
Filippo Costa, Agostino Monorchio, Salvatore Talarico +1
In this letter, an approach for designing a tunable and steerable antenna is presented. The antenna model is based on a wideband bow-tie radiating element mounted above an active A…
A Thin Electromagnetic Absorber for Wide Incidence Angles and Both Polarizations
Olli Luukkonen, Filippo Costa, Agostino Monorchio +1
In this paper a planar electromagnetic absorber is introduced whose performance is maintained over a wide change of the incidence angle for both TE and TM polarization. The absorbe…
