Four Arms Koch Curve Multiband Cross Antenna

The current upsurge in wireless communication systems has forced antenna engineering into facing new challenges, which include the need for multiband, small size, good performance, easy implementation and low- cost antennas. In modern terminal antenna technology there is an increasing need for single fed antennas operating in more than two frequency bands. In this paper, a crossed dipole antenna combined with the Koch curve geometry which has a novel configuration, is proposed and investigated for low profile and multi-band performance in mobile communication systems. This antenna has novel multiband performance in addition to the simplicity of implementation. All simulation results and modeling of the antenna performed by using moment-method based simulation code (NEC-Win professional). The advantages and disadvantages of this antenna are presented and discussed with an emphasis on the multiband characteristics of the proposed antenna.
