Genetically Engineered Multiband High-impedance Frequency Selective Surfaces
نویسندگان
چکیده
A methodology is presented for the design synthesis of metamaterials that act as thin multifrequency artificial magnetic conductors. These structures are realized by placing a frequency-selective surface above a conventional prefect electric conductor, separated by a thin dielectric layer. The frequency-selective surface design is optimized using a microgenetic algorithm to operate at multiple, narrow frequency bands. Two examples of genetically engineered multiband high-impedance frequency-selective surfaces (that is, artificial magnetic conductors) are presented and discussed. © 2003 Wiley Periodicals, Inc.

Artificial magnetic conductors realised by frequency-selective surfaces on a grounded dielectric slab for antenna applications
New designs of artificial magnetic conductors (AMC), including hard and soft surfaces and dual-polarised high-impedance surfaces are realised by printed dipole/slot frequency-selective surfaces (FSS) implemented on a grounded dielectric slab. Multiband designs of hard and soft surfaces are proposed based on the use of FSS structures with different resonance lengths and orientation of dipoles/sl...

This paper presents the design & analysis of a planar multiband antenna (Iterated Pythagorean fractal tree antenna) with impedance steps in base path. Impedance steps are adopted with finite ground plane for better impedance matching, multiband & bandwidth characteristics as compare to non-iterated form. As tree iteration increases new resonance frequency will obtained, Iterated Pythagorean fra...

متن کاملFractal FSS: a novel dual-band frequency selective surface - Antennas and Propagation, IEEE Transactions on
The multiband properties of self-similar fractals can be advantageously exploited to design multiband frequency selective surfaces (FSS). A Sierpinski dipole FSS has been analyzed and measured and the results show an interesting dual-band behavior. Furthermore a near-field measurement technique is applied to characterize the FSS response to different angles of incidence. Finally, it will be sho...
متن کاملMultiband Slot Loaded Uniplanar CPW-fed Monopole Antenna with Asymmetrical Arms
This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...
