“…an operating wavelength  0 of 50cm. This represents a figure of merit of about 6.7, where the figure of merit is defined as d 0  , [10,11]. NEC calculated the boresight gain of this antenna to be about 1.7dBi which, as expected, is equal to that of a Hertzian dipole.…”

The Genetic Algorithm technique has been used to optimize the design of small folded wire antennas. The genetic optimizer located wires on a predefined grid to create well matched devices operating at single or multiple bands. The chromosome structure and the fitness function employed are described. The GA approach also enabled broadband radiators and electrically small convoluted geometries to be designed.

3-D printing is a technology that enables the fabrication of complex objects directly from a digital model. Folding the elements of Frequency Selective arrays in three dimensions gives a significant reduction in the resonant frequency for a given cell dimension, and such structures are candidates for additive manufacture. The aim in this paper is to demonstrate by example the development of novel electromagnetic structures that could be fabricated in parallel and integral with the additive manufacture of buildings, for electromagnetic architecture control. The principle is illustrated with two new geometries based on dipole and loop elements. The cores of these structures were fabricated with a 3-D printer that uses a plaster-based material. Theoretical and experimental results confirm the operation of the surfaces within the UHF frequency band.Index Terms-3-D printing, Additive manufacture, electromagnetic architecture, electromagnetic wave propagation, frequency selective surfaces.

“…The proposed square loop FSS is very popular and one of the fundamental FSS shapes. However, switching this structure as a function of time did not get much concern as the ring loop structure [1,2]. In this work a new square loop FSS is designed with only one active element required for switching unlike other references in literature which requires two active elements per unit cell [4].…”

Abstract-A switchable square loop frequency selective surface (FSS) design is presented. The FSS is switched between reflective and transparent state by using one gap for each unit cell. Measured and simulated results are compared. PIN diodes are integrated to the FSS for electrical switching. The PIN diodes equivalent circuit capacitance element is varied to investigate its effect on the switchable FSS performance. The switchable FSS power percentages of the reflected and transmitted states are presented in tables and discussed.
