Abstract: A printed dual broadband monopole antenna has been presented here for WLAN and WIMAX applications. The antenna is designed with the help of simulation software HFSS and proposed antenna is fabricated to verify the simulated results with the measured results. The patch of the proposed antenna consists of two identical metallic structures which are like English letter “E” and are placed face to face to each other. Now, the lower arms of E-shaped structures are connected together with a rectangular microstrip transmission line of length 15 mm and width 3.06 mm to form the proposed patch. The proposed “E” shape patch is printed on FR4 substrate of height 1.6 mm, relative permittivity εr= 4.4, and loss tangent 0.02. The ground plane of the proposed antenna consists of partial rectangular metal at opposite side of the patch. The proposed antenna achieves dual band characteristics using the proposed structure. The measured results show that the proposed structure covers the transmission bands from 2.45 GHz to 3.66 GHz with center frequency of 3.0 GHz and from 4.16 GHz to 5.94 GHz with center frequency of 5.37 GHz. There is a good impedance matching between measurement result and computer simulated results. The measured percentage bandwidths have been obtained by 39.1 % and 35.24 %, respectively. The peak gain (measured) at 3 GHz and 5.37 GHz resonant frequencies are 3 dBi and 4 dBi, respectively. This proposed antenna also exhibits with monopole like E-Plane and H-plane co-polarization radiation pattern at two center frequencies. The obtained bands are useful for WLAN and WiMAX applications.
