TL;DR: Partially reflecting surfaces with positive reflection phase gradients are investigated for the design of wideband, low profile electromagnetic band gap (EBG) resonator antennas in this article, where three such surfaces, each with printed dipoles on both sides, have been designed to obtain different positive reflection phases and reflection magnitude levels in the operating frequency bands.

TL;DR: In this article, a resonator antenna made from a complex artificial surface and a metallic ground plane is described, which is realized using a woodpile electromagnetic bandgap (EBG) material, and the antenna has a frequency dependent reflection plane location.

TL;DR: In this article, an efficient approach to achieve the shielding effectiveness (SE) by using a frequency-selective surface (FSS) is presented, which consists of cross dipoles and rings printed on the opposite sides of a single-layer FR-4 substrate, exhibits a wide, 7.5GHz stopband to provide simultaneous shielding in both X and Ka-bands.

TL;DR: Thin, broad-band, E-shaped microstrip patch antennas (ESPAs), operating in the 5-6 GHz frequency range, are presented, suitable for WLAN adaptor cards in the PCMCIA format, allowing users of current notebook computers to upgrade to this high-speed wireless standard at a low cost.

TL;DR: In this paper, the beam of a resonant cavity antenna is steered by transforming phase of the antenna near field using a pair of totally passive metasurfaces, which are located just above and parallel to the antenna.
