Abstract(in English) | In recent years, There is a problem which may occur intersystem interference by implementing of wire-less systems in the same housing. Reason why there is only a difference of about 100MHz center frequency in wireless LAN and WiMAX. Previously, antenna had realized only the shape of the ground plane of the antenna placement and isolation has been achieved in the filter. In this paper,we investigated possibility for the shape of the ground plate and the placement of the antenna in order to reduce the interference between the systems of the communication methods used close frequency band. Specifically, the ground plate was determined cut in accordance with the current distribution of the antenna ground plate and combination of antenna position. Isolation of the 2.4GHz band antenna from 2.5GHz band was found to be 21.36dB from numerical analysis. Vice versa it was confirmed that the high isolation of 49.77dB can be obtained. |
