Abstract

In this paper, a fork shaped MIMO antenna has been proposed with an overall size of 26×40×0.8 mm , that is essentially used for the Ultra-WideBand (UWB) applications. It is fabricated on the FR_4 Epoxy substrate. The material has a dielectric constant of 4.4 and a loss tangent of 0.02 and the most important fact is that, it is very cheap and easily available. The proposed antenna consists of two fork shaped patch on the top surface of the substrate with a microstrip feed of 50Ω is positioned perpendicular to each other to attain good isolation. To increase the impedance bandwidth and to improve the isolation, two long ground stubs are placed on the bottom surface of the substrate. A small strip is used to connect the two ground planes together to form the common ground at the bottom surface. The performance of the fork shaped MIMO antenna can be measured in terms of the reflection coefficient at the two input ports, coupling between the input ports, peak gain and radiation pattern. The results show that the fork shaped MIMO antenna has an impedance bandwidth greater than 3.1 to 11.1 GHz with a low mutual coupling less than -15 dB throughout the band. It has a VSWR of less than 2, throughout the band and it has a good gain and an omnidirectional radiation pattern.
