Body-worn communication devices have attracted much attention due to their wide applications. In this regard, various wearable antennas that have lots of advantages have been designed by researchers in recent years. Metamaterials that have negative refractive index can also be used in the wearable antenna designs because they have an ability to eliminate harmful health effects. In this study, a metamaterial-based wearable microstrip patch textile antenna operating in industrial, scientific, and medical bands was designed and simulated. The radiation values of this antenna were analyzed. Then metamaterial-based electromagnetic band gap (EBG) structure and wearable antenna integration was designed. Two different integrated antenna designs (3 × 3 and 5 × 3) were proposed. We obtained the performances of these antenna designs and calculated the specific absorption rate (SAR) values. We calculated the absorbed power 48.8, 0.167, and 0.0485 W/kg for 10 g tissue of wearable microstrip patch antenna, EBG integrated wearable antenna with 3 × 3 design, and EBG integrated wearable antenna with 5 × 3 design, respectively. Because the SAR values of the EBG integrated wearable antenna designs are well below the standard values, we can say that the designs proposed in the study can be used in many areas, such as military, health monitoring, and wireless communication.

Microstrip antennas that can operate in single and multiple frequency bands are required in various wireless communication devices. A single patch, square shaped microstrip patch antenna having high directivity and gain is proposed in this paper. The geometry of proposed antenna is optimized using Genetic Algorithm (GA) to operate in X-Band for wideband applications. The proposed antenna design exhibits a wide operating bandwidth 550 MHz (simulated) and 450 MHz (measured), high gain and directivity of about 8.35 dB (simulated) making it suitable for wideband applications. The proposed antenna design works in X-band which has weatherproof characteristics and supports easy communication of voice, data, images and HD videos. The attractiveness of the GA design over the traditional design methods is its ability to achieve the desired performance by using a simple design of single patch antenna.

Microstrip Patch

A microstrip patch antenna is designed for a wearable antenna. The performance of microstrip patch antenna loaded with reactive impedance surface (RIS) is described in terms of gain, bandwidth and return loss. The antenna is investigated in two conditions which are conventional microstrip antenna with RIS and without RIS. The designed antenna is also aimed at size reduction therefore it will be suitable for a wearable application. This antenna which is made fully using textile and it is designed for operation in the 2.45 GHz band. The performance of microstrip patch antenna loaded with RIS is described in terms of gain, bandwidth, return loss and radiation pattern. The antenna designed with RIS operates at 2.45 GHz. Bandwidth enhancement is achieved with RIS where the designed antenna can cater frequency from 2.4 GHz to 3 GHz. A gain enhancement is achieved of 20% is achieved compared with the conventional patch antenna. Although the size of the patch is reduced with the introduction of RIS, the overall size of the antenna with the substrate is almost similar to the conventional patch antenna. However, the performance of the antenna is greatly enhanced with the use of RIS.

This paper investigates the numerical and experimental analysis of a low-cost and dual-band microstrip patch antenna for the fifth generation (5G) mobile communications. The numerical analysis of the proposed antenna is performed using the computational electromagnetic simulator (CEMS) software which is based on the finite-difference time-domain (FDTD) and CST software which is based on the finite integration technique (FIT). The performance of the proposed antenna designed and fabricated on a low-cost FR-4 substrate is verified with the simulated and measured results. The antenna operates at dual frequency bands which are 24 and 28 GHz. The antenna maximum gain values are 3.20 dBi and 3.99 dBi in the x-y plane at 24 and 28 GHz, respectively. The proposed antenna provides almost omni-directional patterns suitable for 5G mobile communication devices.
