Opis:: A Yagi plasma antenna model was established by HFSS according to the relationship between plasma dielectric constant and electron density. The patterns were simulated by changing plasma parameters and the number of director dipoles. Results show that when the passive vibrators were switched off, the antenna is omnidirectional antenna. The directionality increases with the increase of the number of passive dipole and the main lobe of which narrows down. Then the plasma Yagi antenna model is established by plasma tube, the gain changed by changing the number of passive dipoles, so the plasma Yagi antenna has a very good reconfigurability. Results prove that the feasibility of the plasma Yagi antenna can be used on AIS base station of Ships’ Routeing waters. It can promote the communication and capability of maritime supervision in Ships’ Routeing waters.

Tytuł:: Evaluation of near field of the GSM base station antennas in urban environment
Autorzy:: Wójcik, D.

Opis:: A simple and efficient method for evaluation of near field of the GSM base station antennas in urban environment is presented in this paper. The method is based on the replacement of panel antenna with a discrete linear array. Moreover, the geometrical optics approach is used to consider the influence of environment. The approximate results are found to be in excellent agreement with the results obtained by using the method of moments (MoM). Presented method can be successfully used for fast evaluation of exposure to electromagnetic fields emitted by the GSM base station antennas in urban environment.
