“…Another issue is a large number of geometry parameters typical for modern antennas, which by itself makes simulation-driven design closure a challenging task. Methods such as the gradient-based search with numerical derivatives [1] or population-based metaheuristics (often used for global optimization [2,3]) may be prohibitively expensive. A possible way of alleviating these difficulties are surrogate-assisted techniques [4,5] as well as the gradient search with adjoint sensitivities [6,7].…”

Re-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various substrates is presented. The proposed approach is based on inverse surrogate modeling with the scaling model constructed for several reference designs that are optimized for selected values of the substrate permittivity. The surrogate is set up at the level of coarse-discretization EM simulation model of the antenna and, subsequently, corrected to provide prediction at the high-fidelity EM model level. The dimensions of the antenna scaled to any substrate permittivity within the region of validity of the surrogate are obtained instantly, without any additional EM simulation necessary. The proposed approach is demonstrated using an ultra-wideband monopole with the permittivity scaling range from 2.2 to 4.5. Numerical validation is supported by physical measurements of the fabricated prototypes of the re-designed antennas.

“…Concerning the issue of the antenna size reduction, fractal shapes have been widely investigated [19,20,21,22,23,24] since they also constitute a reasonable solution for yielding a multiband behavior thanks to the selfsimilarity and space-filling properties. The Sierpinski gasket is one of the most extensively studied fractal reference shapes and it is an excellent candidate for the synthesis of multiband radiators.…”

A compact planar multiband antenna for 3G/4G mobile terminals is presented. The proposed design consists of a Sierpinski Gasket fractal geometry perturbed according to a Particle Swarm optimization (PSO) strategy in order to operate in advanced wireless services (AWS-1, 1710-1755 MHz, 2110-2155 MHz) and worldwide interoperability for microwave access (WiMAX, 3300-3600 MHz) bands. Numerical and experimental results assess the effectiveness of the proposed prototype in its multiband operations fitting the project constraints.

“…RFID tag antennas on metallic surfaces change the boundary condition, radiation pattern, efficiency, input impedance, gain, read range, and resonant frequency. To solve this problem, many researchers have developed other RFID antennas, including on metallic surface such as a wideband RFID tag antenna for metallic surfaces [8], orthogonally proximitycoupled patch antenna for a passive RFID tag on metallic surfaces [9], a RFID tag antenna for metallic surfaces using lossy substrate [10], a h-shaped tag antenna using microstirip feed design on metallic objects [11], loop antenna with interdigital coupled section on metallic objects [12], a UHF RFID/GPS fractal antenna for logistics management [13], a metallic RFID tag design for steel-bar and wire-rod management application in the steel industry [14], small proximity coupled ceramic patch antenna for UHF RFID tag mountable on metallic objects [15], a metal plane on a meandered slot antenna [16], and a RFID tag metal antenna on a compact his substrate [17]. RFID systems increase steadily being published in many applications, but RFID technology of the steel bar and object industry is slow in progress.…”

Abstract-In this paper, we propose a novel UHF RFID coupled slot metallic tag antenna with a radome. The proposed tag antenna consists of a frequency tuning slot, imaginary part tuning slot, real part tuning stub, micro-chip, and radome. The RFID tag antenna was designed and fabricated for use in the Korean and Japanese UHF band of 916.7 to 923.5 MHz. The measured 3 dB frequency bandwidth is 914 to 926 MHz. The measured read range is 11.5 m on a metallic surface. Details of the proposed tag antenna design, as well as simulated and measured results are presented and discussed.
