Abstract
A compact planar log-periodic dipole array (LPDA) antenna operating from 0.8 to 2 GHz with loading dielectric materials and top-loading techniques is proposed for high gain application and miniaturization of the antenna. The antenna is composed of top-loading dipoles and parallel stripline printed on a substrate dipoles periodically loading the Taconic CER-10 material which are placed on the both side of the antenna. Furthermore, in order to enhance the bandwidth performance effectively, a trapezoidal stub is also applied into the design as impedance matching techniques. The proposed antenna is especially suitable for the lower band of the antenna's operating frequency range. The simulated results of the antenna such as the gain and S parameter are given.
