A Compact two port MIMO Antenna for UWB Application

In this paper, two parallel excited hexagonal patch antennas are printed over a lossy dielectric of relative permitivity 4.4 and dimension L=32mm, W=15.96 mm and h=1.565mm. In order to operate in MIMO, S11 and S22 though had better matching at 4.25 GHz and 10.08 GHz, the isolation S21 had to be above -15dB. At the operating frequencies, the proposed design is observed to have an omnidirectional radiation pattern in the H-plane.
