The technology of metallized foam offers a new approach to design wire-like, flat, and 3D antennas. Only the necessary metal skin depth (some microns in UHF band) is deposited over arbitrary shaped structures. Thanks to this technology, new antenna d

The design of a highly directive metamaterial-based cav- ity antenna for a 2.46 GHz application is reported. The proposed struc- ture is evolved from a Fabry-Perot (FP) cavity with a patch antenna acting as the feed and four metallic walls on the lat

We present the design and characterization of a triband low-profile antenna based on the use of artificial magnetic conductor (AMC) surfaces. The engineered double AMC substrate allows reducing the separation between the radiating element and the gro

An original configuration of low-profile directive antennas is presented in V-band. The focusing effect is performed by a plane-parallel Fabry-Perot (FP) resonator illuminated by a printed antenna. Both reflecting mirrors are made of metal strip grat

Radiation characteristics and performance of Gaussian beam antennas (GBAs) are studied theoretically and experimentally in the 60 GHz band. A GBA consists of a plano-convex half-wavelength Fabry-Perot (FP) resonator excited by a guided source with a
