Abstract

This paper presents the design and parametric study of a tunable dual band square slot antenna with stub for DSC, ISM, and WiMAX applications. This dual band antenna has an ability to be tuned to any of the mentioned bands, according to the required applications, depending on the length of square side and the stub. The overall size of the designed antenna is 50mm × 50mm. The antenna has been etched to an epoxy FR4 substrate with a relative permittivity of 4.4 and a thickness of 1.6 mm. A parametric study has been presented for the stub. The design equation for the lower band and the design curve for the upper band are obtained. The resulted radiation patterns have been shown for different frequencies which give the antenna a good characteristic to be candidate as a dual-band antenna for the aforementioned applications. A commercial High Frequency Structure Simulator (HFSS), ver. 15, has been used to analyze the design parameters.
