“…Figure shows an example of reflector with a four frequency FSS . The FSSs with multiband characteristic work as subreflectors for satellite communication, so a single main reflector can distribute different frequency bands . To realize the FSS with a multiband characteristic, the multiresonant elements in a single layer are arrayed, or a multilayer FSS is used, and especially the double layer FSS (DFSS).…”

In this article, a double layer frequency selective surface (DFSS) composed of ring patch elements of four different sizes is proposed, to obtain angle and polarization insensitivity, and a broad bandwidth. The multiresonant elements with different sizes are then arranged into a unit cell that is to be repeated periodically. The proposed DFSS reflects the X and K‐band signals, while allowing the C‐ and Ku‐band signals to pass through. In this design, a four‐band FSS (including band‐stop FSS and band‐pass FSS) with a broad bandwidth is obtained, by adjusting the sizes of the rings, and thickness of the air foam between the FSS layers. Experimental verifications are carried out. The computed results agree well with the measured ones. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:547–552, 2014

“…In the FSS, two or more layer structures are widely used to realize a broader bandwidth. A typical example of a double layer structure is the so‐called DFSS structure . The DFSS is separated by a thick layer of dielectric with a low relative permittivity, such as air foam.…”

“…Several variables, such as the shape, spacing and orientation of the unit cells, and the properties of the dielectric, must be simultaneously adjusted during the design process to achieve acceptable stopband or passband characteristics. Although traditional FSSs exhibit a single, narrow stopband or passband characteristic, multiband FSSs have been demonstrated [2]- [10] that use multiply resonant structures such as fractals, or multiple layers of elements, with two or more FSS screens backed by dielectric layers. The design costs for these structures is significant, requiring a time consuming trial and error process in simultaneously tuning the elements of the periodic surface and the characteristics of the dielectric.…”

A self-tuning electromagnetic shutter is introduced, consisting of a slotted metallic surface with computer controlled switches placed across the slots. By opening and closing the switches, the transmissivity of the surface may be adjusted over a broad range of frequencies. In particular, the surface may be placed into open and closed states, creating an electronically-controllable shutter. The ability of the shutter to act as an open or a closed surface over a broad range of frequencies, incidence angles, and polarization states is investigated using simulations and measurements, and the feasibility of the system is thereby demonstrated.

“…Slot-coupled microstrip antennas [1][2] are possible candidates because they can provide antenna gain of 6 -10 dBi and are easily integrated with circuit components. Several single-feed designs for slot-coupled microstrip antennas operating at two different frequencies have been reported [3][4][5]. In these designs, antennas with frequency ratios that are different …”

The frequency‐selective property of an array of rectangular dipole microstrip patches, resonant at two frequencies in the J band and two other frequencies in the Ku band, has been investigated experimentally. Measured data indicate that the electromagnetic wave transmits well through the frequency‐selective surface (FSS) in the frequency range of 8.2 to 11.4 GHz and scatters well (around 20 dB) from the FSS in the frequency ranges of 6.3 to 7.7 GHz and 12.4 to 13.9 GHz. © 2004 Wiley Periodicals, Inc.
