“…The analyzed planar structure was modeled with the help of the numerical modeling program HFSS from ANSYS as it can be observed in Figure2.The antenna consists of a flexible dielectric, polyimide, with a relative permittivity of 3.5 [17].On the upper side of this dielectric the dipole and directors are constructed, while on the other side there is the reflector. The initial dimensions in mm of all the elements can be seen in Figure 3.…”

The paper follows the construction of a planar Yagi Uda antenna and the influence of the geometrical parameters on its characteristic parameters. According to the studies conducted on classical Yagi Uda antennas, modifying their geometrical parameters can lead to the improvement of the antenna function. Thus, the authors will consider modifying the number of directors, the distance between the fed dipole and the first director, the distance between the directors and the length of the directors in an attempt to determine their influence on the antenna’s characteristic parameters. All the results are compared and the similitude between planar and classical antenna is highlighted. Some of the most important antenna parameters were analyzed namely S parameters, gain, directivity, frequency bandwidth and radiation pattern.

“…In this paper, the influences of the circular patch antenna's electromagnetic fields emissions on the human head are analyzed, considering that this type of antennas can be found in the devices that are very often used by people. In our research activities different types of antennas were high frequency analyzed to find their parameters [1][2][3][4][5][6][7].…”

The influences of the antenna’s emissions on the human body are to be investigated because in our days, as a simple example, the mobile phone is permanently in use, on day or night. The long-time human exposure at the electromagnetic field radiations is obvious and there exist the possibility that these can affect the human health. The influences of the circular patch antenna’s emissions on the human head are analyzed at high frequency in this paper. First the patch antenna is modelled and simulated to extract its specific parameters and to represent the emitted electric and magnetic field around it. Next the human head is considered near to the patch antenna in position that imitates the mobile phone at ear and the electric field, the magnetic field, and the specific absorption rate (SAR) are represented to determine the antenna’s emissions at its operating frequency. So, the main aim of the paper is the high frequency analyzes of the circular patch antennas to investigate the influence of their emissions on the human head. The results obtained are compared and reported to the standards and legislation in force on human occupational exposure, to verify that the limits are met.
