In this paper, a simple and practical electrically small planar unipole antenna is presented, and the dependences of input impedance on dimension of the antenna and frequency are investigated. The design of the antenna is analyzed by using the finite element method. The special case experiment verification is performed to ensure the effectiveness of the numerical model. Based on the comparison and analysis in detail, the effective design method for this sort of electrically small antenna is given.
