TL;DR: In this paper, a three layer structure composed of three metal layers, separated by two electrically thin dielectric substrates, is proposed for conformal frequency selective surfaces. But, unlike traditional third-order bandpass FSSs, which are usually obtained by cascading three identical first-order frequency selective surface (FSSs) a quarter wavelength apart from one another and have thicknesses in the order of lambda/2, the proposed structure has an extremely low profile and an overall thickness of about lambda/24, making it an attractive choice to conformal FSS

TL;DR: In this paper, a new technique for designing dual-band frequency selective surfaces with arbitrary bands of operation with second-order band-pass responses at each band of operation is presented and experimentally verified.

TL;DR: In this article, a dumb-bell shaped defected ground structure (DGS) was successfully used to reduce the mutual coupling of a two-element microstrip antenna array with respect to a single antenna.

TL;DR: In this article, the authors investigated the effect of DGS to mutual coupling reduction of a two-element microstrip antenna array and compared the proposed DGS antenna with other techniques and showed that the proposed antenna has an exceptionally lower mutual coupling between two E-plane coupled elements.

TL;DR: In this paper, the authors present an efficient technique to realize a high-rate direct binary FSK modulation by using the transient properties of high-Q antennas, where the natural resonance of a narrowband resonant-type antenna is switched at a high rate, and the radiating signal follows the variation of resonant frequency and provides a highrate data-transmission regardless of the narrowband characteristics of the antenna.
