Abstract

In this paper, a novel log periodic cantor koch dipole antenna(LPCKDA), which is composed of the cantor Koch dipole elements instead of the Koch dipole elements, is proposed to reduce the size of the log periodic koch dipole antenna(LPKDA). To investigate the reliability of the proposed antenna, the LPCKDA is designed and analyzed at 0.5~1.5 GHz and compared with the LPKDA(Log Periodic Koch Dipole Antenna) characteristic. It is shown that although the proposed LPCKDA has a decreases of 5 % in the length of the dipole elements, radiation characteristics of LPCKDA are similar to radiation characteristics of the LPKDA.
