Abstract

In this paper, design of a low-profile, coplanar waveguide fed elliptical patch Super Wide Band (SWB) multiple input multiple output (MIMO) antenna for various applications are presented. Two planar elliptical patch antennas with Microstrip-feed are used as the elements of the MIMO antenna. PTFE (Polytetrafluoroethylene) is used as dielectric substrate whose relative permittivity is 3.5. The proposed antenna occupies a fractional bandwidth of more than 172.12% (2.2473-30 GHz) which covers frequency range for all types of UWB applications along with some other common wireless communication systems such as ISM, Wi-Fi, WiMax, part of LTE and so on. Performance analysis of designed antenna is carried out in free space in terms of reflection coefficient, radiation pattern and voltage standing wave ratio (VSWR) and the results show that, this antenna could be a very suitable one for above mentioned applications.
