A topology optimization method is proposed in this study to miniaturize a Rectangular Microstrip Patch Antenna (RMPA) operates at a frequency of 2.4 GHz using Metamaterials (MTMs) composed of complementary resonator. The metamaterial is placed in an intermediate layer between the patch and the ground, binary pixelation approach is used to build the structure of the complementary resonator and it is optimized using the Genetic Algorithm (GA). The conventional patch antenna and the proposed patch antenna are designed and simulated using High Frequency Electromagnetic Field Simulation (HFSS) software. A comparison between results of the two antennas is done. The area of the proposed patch antenna is reduced about 73.6% compared with the conventional patch antenna, and the return loss is improved from −18 dB to −35 dB.

Abstract-Use of discontinuities in microstrip lines is currently employed to improve the performance of different passive circuits, including size reduction of amplifiers, enhancement of filter characteristics and applications to suppress harmonics in patch antennas. This paper presents an improved method of size reduction of a microstrip antenna using Defected Microstrip Structure (DMS) that it is used to perform serious LC resonance property in certain frequency. The DMS is integrated in antenna structure, and therefore this method keeps the antenna size unchanged and makes a resonance frequency. This resonance is due to the abrupt change of current path of antenna that resonates at 5.8 GHz which is shifted to 2.69 GHz thanks to spiral DMS. A prototype of the antenna was fabricated with an FR4 substrate and tested.

“…Microstrip antennas are vastly used in satellite, aviation, military and various commercial applications, due to their suitable size, price, having a good performance and easy for installation. Accordingly microstrip antennas are more nominated to serve as miniaturized antennas and many attempts are devoted for reducing microstrip antennas in size such as using Defected Microstrip Structure (DMS), Defected Ground Structure (DGS), a dielectric substrate of high permittivity at the ground plane or a combination of them [1,2] 78 metamaterial and fractal method [3,4]. Some researchers replaced the traditional substrate by a µ-negative metamaterials (MNG) which miniaturize the size of a rectangular patch antenna to 77% [5] Meandering the microstrip feed line has been used in a previous work to perform impedance matching over a very wide band range of frequencies.…”

Recently the demand for compact size devices has been increased whether being used for sensor networks, smart phones, smart watches or RFID tags etc. One of the most important parts of these systems is its antenna which facing a big challenge of having a low profile that meets the required size of these wireless communication devices. This paper presents a design of a simple planar strip monopole antenna for WLAN application.Miniaturization has been performed on this antenna via two different techniques. Firstly corrugations were added to both side edges of the radiating strip that reduced the size with 10.7% of the original size. Secondly the radiating strip has been meandered to increase the size reduction to about 14.28%. Both simulation and measured results shown that meandering technique was more efficient in miniaturizing the size of the designed antenna due to forcing the current to follow a meandered path that rise up with shorter height.
