| Abstract | ||
| In latest years the progress and employment of wearable antennas have developed quickly for human monitoring applications. Due to shrink of wireless communication equipment reasons, the microstrip patch antennas with size-reduced are preferred. In this paper, two wearable antennas with different shapes (similar to the button) are introduced. These are compatible for a commercial wireless system platforms such WiFi and WiMax standards. The proposed antennas are very suitable for child indoor monitoring purposes. Here, because of the small size of these antennas (the largest dimension approaches to 25 mm), the assumption of bending the surface, substrate and ground layer are neglected. The operation frequency band for the first antenna is between 5.4 and 5.6 GHz, while its between 3.6 to 3.8 GHz for the second and both with a linearly polarized radiation. For a wearable antenna, a conductive textile was used for the substrate layer, a permittivity of 4.4 is used. A 52% size reduction result of the rose patch size (the 2nd antenna) compared to the size of a regular rectangular patch antenna (the 1st antenna) additionally, investigations had been conducted for different antenna without bending and the antenna’s performance in vicinity to human body. The proficient multiphasic COMSOL software is used for simulation. | ||
