A Dual-band MIMO Antenna for Bluetooth/WiMax/LTE Applications

A dual-band microstrip-fed planar MIMO antenna is proposed for application in Bluetooth (2.4 GHz), WiMax (2500MHz/ 3650MHz) and LTE (2570MHz-2620MHz/ 3600MHz-3800MHz) bands. A triangular ring resonator with a split at asymmetry position is used to realize dual-band response. The antenna provides two resonances at 2.6 GHz and 3.7 GHz. The structure is simulated and studied for S-parameters, envelop correlation coefficient (ECC), channel loss capacity (CCL), diversity gain (DG), radiation patterns and gain values, and the results are presented and discussed throughout the paper. The structure is fabricated and results are compared with simulated results to validate the simulation. The simple design of this proposed antenna and its miniaturized dimension reveals significance of this design.
