UWB-MIMO Antenna with High Isolation Using Stub Dedicated to Connected Objects

Abstract

In this communication, a Ultra-Wide-Band (UWB) Multiple-Input Multiple-Output (MIMO) antenna with high isolation is exposed. Each antenna element consisting of simple microstrip fed square radiation patch with partial ground plane. Two UWB MIMO antennas with entire dimension of 80 x 100 mm2are simulated. Simulations results denote that the suggested antenna system operating at a frequency range 1.4-10.6 GHz, and the coefficient of decoupling is always inferior to -16.5 dB. A partial ground is employed to design an UWB antenna and the isolation has been enhanced by inserting a stub.
