A study on design of antenna for PAN application

Our concern regarding wireless PAN(Personal Area Network) and its application by using Bluetooth has increased significantly in recent years. There are diverse factors which affect the RF characteristics of Bluetooth application, accordingly the research which can advance a performance of application by improving properties of the antenna is carried. In order to advance a RF performance as an interface of wireless PAN environment, a novel antenna is proposed to operate at both 2.45 GHz and 5.8GHz and provide sufficient bandwidth for lower ISM band in which Bluetooth operates[1], Wibro band and upper ISM band which will be served in the future. The proposed antenna is advantageous for MMIC and LTCC using CPW feeding method. The proposed antenna includes the present Bluetooth band and 5 GHz ISM band, for that reason it can be applied to various applications.
