“…However, it is very difficult to find a global optimum using only TM because an OA consists of a limited number and limited level sizes of design variables [4]. In order to resolve the drawbacks of TM, hybrid methods have been introduced [5][6][7]. In one study [5], a hybrid method which combined TM with an evolution strategy (ES) was proposed.…”

Hybrid robust optimization that combines a genetical swarm optimization (GSO) scheme with an orthogonal array (OA) is proposed to design an antenna robust to the tolerances arising during the fabrication process of the antenna in this paper. An inverted-F antenna with a metal frame serves as an example to explain the procedure of the proposed method. GSO is adapted to determine the design variables of the antenna, which operates on the GSM850 band (824-894 MHz). The robustness of the antenna is evaluated through a noise test using the OA. The robustness of the optimized antenna is improved by approximately 61.3% relative to that of a conventional antenna. Conventional and optimized antennas are fabricated and measured to validate the experimental results.

“…were used. [35][36][37][38][39] Different from the traditional rubber-based MR elastomers, the position of the magnetic particles in the above MR materials are movable and they can transform from isotropic to anisotropic under applying an external magnetic field, which enable them exhibit high mechanical properties. 37 Therefore, the soft polymer matrix with low initial modulus is desirable for improving the MR effect.…”

Different fractal antennas based on aperture coupled feeding technique are studied, analysed and compared for size reduction, low profile, and good omini-dirctional pattern suitable for RFID applications. The results are used as a guideline to propose modified fractal shapes patch antennas having lower size reduction parameters. All the designed antennas are based on zero-order square patch antenna where different fractal geometries are introduced to miniaturize the size of antenna for 5.8 GHz band. A maximum reduction in patch antenna size of 59.80 % is achieved when using modified Minkowski pre-fractal patch antenna.
