Design of a mimo rectangular dielectric resonator antenna for LTE application
A Broadband Multiple-Input-Multiple-Output (MIMO) Rectangular Dielectric Resonator Antenna is design and implemented. The proposed antenna consists of two ports (Aperture coupled microstrip fed using slot and Coaxial-probe) and a limited ground plane extruded on the substrate. The overall size of pr...

| 總結: | A Broadband Multiple-Input-Multiple-Output (MIMO) Rectangular Dielectric Resonator Antenna is design and implemented. The proposed antenna consists of two ports (Aperture coupled microstrip fed using slot and Coaxial-probe) and a limited ground plane extruded on the substrate. The overall size of proposed substrate is70×60 and the size of rectangular dielectric resonator antenna is38×54×15 . The antenna is fabricated on inexpensive FR4 a dielectric constant of e =4.3, loss tangent tan d=0.019 with thickness of 1.6-mm. The measured results represents that the proposed antenna obtained a reasonable bandwidth from 1.8 GHz to 2.6 GHz that could cover LTE bands application defined by 10-dB return loss. Furthermore, S-Parameters ( , , ) of antenna are simulated and measured. In this project, merging the resonance frequency from the feeding mechanism and the radiating structure with assigning the air gap between DRA and substrate has been employed to broaden the bandwidth. Since both the DRA and slot radiate like a short magnetic dipole, high gain and directivity can be achieved. Simulation and measurement on the final prototype antenna were carried out and compared. |
