Abstract

In this paper, a crossed dipole antenna combined with the first iteration quadratic Koch curve geometry, which has a novel configuration, is proposed and investigated for low profile and multi-band performance in communication systems. The proposed antenna has operating frequencies of 1255 MHz, 2058 MHz, and 6450 MHz. The field pattern of the proposed antenna is described and simulated in the three planes: XZ-plane, YZ-plane, and XY-plane. The radiation characteristics, VSWR, reflection coefficients, polarization, and input impedance of the proposed antenna are described and simulated using the 4NEC2 software package. Also, the gain of this proposed antenna is calculated and described in the three planes: XZ-plane, YZ-plane, and XY-plane, where the antenna is placed in the YZ-plane.
