This paper presents a new multiband antenna is proposed for Wireless communication. Commercially available software High Frequency Structural Simulator (HFSS) and Computer Simulation Technology (CST) microwave studio was adopted in this investigation. The presented antenna consists of a slotted rectangular patch with a rectangular ground plane.
The antenna exhibits four resonates at 2.05 GHz, 2.45GHz, 3.54GHz and 4.23 GHz. The antenna has been printed on FR-4 (lossy) Substrate with 4.6 of relative Permittivity and 1.6 mm of thickness. In addition, the specific absorption rate (SAR) analysis has been analyzed for the proposed antenna.
