The input impedance characteristics of the broadband umbrella shape printed dipole are investigated. Changed to line antenna equivalently, the printed dipole can be analyzed using the method of moment. Thus the input impedance, E plane pattern and H plane pattern of the printed dipole can be obtained. According to the input impedance, the Balun and matching circuit can be designed. The results are in agreement with the analysis results well. An effective method of analyzing and designing printed dipole is given in this paper.
