Abstract

In this article, a dual band antenna for WiMAX, and c-band applications are designed. The antenna structure comprises of a DGS and a rectangular monopole with a microstrip feedline for excitation. The suggested antenna operates over two bands, with resonance at 2.3 GHz for the WiMAX and at 5 GHz for the WLAN system (IEEE 802.11a standard) and c-band application. The F- shaped antenna with DGS is utilized to enhance the antenna's bandwidth. Here FR-4 substrate is used. The antenna has a compact size, that is 40×28×1.6 mm3. HFSS is used to simulate the antenna. The proposed antenna is assessed using a number of antenna parameters, including return loss, gain, current distribution, VSWR, and radiation pattern.
