Abstract

This paper presents a triple band proximity fed 2x1 array antenna with defected ground plane. The proposed antenna configuration is composed of two radiating elements, and both radiating elements are made of a pattern similar to the first iteration level David fractal geometry. The proposed David fractal 2x1 array antenna is designed and simulated on an FR-4 substrate of thickness 1.6 mm and dielectric constant 4.3 by using the CST Microwave Studio simulation tool. In order to improve the radiation characteristics of the antenna an H-shaped defect is etched in the ground plane. The antenna is fabricated and tested. The experimental data show good agreements with simulation results. The fabricated triple band fractal 2x1 array antenna resonates at 2.527 GHz, 3.329 GHz and 3.742 GHz having bandwidths of 303 MHz, 99 MHz, and 102 MHz, respectively. The proposed fractal array antenna can be used in mobile applications such as Wi-Fi, WLAN, Bluetooth and Wi-Max.
