A Printed Monopole Antenna with Symmetric Meandered Arms for WLAN, WiMAX Applications

In this paper, a planar dual band symmetric Meandered Arms monopole antenna for wireless local area network (WLAN) & WiMAX applications is presented. The antenna consists of two symmetric Meandered arms radiating strip leading to generate two separate resonant modes where the first mode is for the 3.5 GHz band and the second mode is for the 5.2/5.8 GHz band operation. The purposed antenna has a measured impedance bandwidths of 3.39-3.5 GHz and 5.5-5.6 GHz, and owns good radiation characteristics impedance bandwidths, with a compact size of 30×35≥×1.6 mm

. The radiation pattern and resonant frequency are mainly affected by symmetric meandered arms radiating patch and a rectangular ground plane. The CST Microwave studio is employed for designing the antenna. This purposed antenna is fed by a coaxial probe through a SMA connector.
