Abstract

In this paper, a rotated E-slot antenna with modified coplanar waveguide (CPW) feeding is presented to obtain broadband characteristics. The antenna comprises of a planar rectangular patch element embedded with E-slot rotated 90° anticlockwise on the radiating side. The CPW feed is modified by extending the ground plane throughout the substrate to surround the rectangular patch. This structure is capable of generating three separate resonant modes with good impedance matching. The antenna is designed on an FR4 substrate of 1.6 mm thickness, covering bands from 3.4 to 3.6 GHz for LTE and 3.4–3.694 GHz for worldwide interoperability for microwave access (WiMAX) systems. The proposed antenna provides good return loss S11 and impedance behavior.
