Summary:
The FDTD becomes a powerful tool for analyzing electromagnetic problems with high level of accuracy. Diversity transmission/reception is performed by using independent antenna elements for the Tx/Rx channels to form a multi-element antenna arrays (MEA). This requires an accurate study of the mutual coupling between antenna elements. In this paper, an FDTD model for microstrip patch antenna element as well as for antenna array with mutual coupling effects is established. An investigation for the mutual coupling between different antenna classifications/arrangements is studied. Multiple subarray element arrangements are used to compare the coupling for E-plane, H-plane and Orthogonal-plane arrangements. The effect of changing the dielectric constant as well as the substrate thickness on mutual coupling level is studied. Different feed techniques are used to investigate the feed effect on the coupling level. The mutual coupling for different field polarization directions is also studied. Finally, an array designer aid tool is concluded to help in building a diversity reception microstrip multi-element array antenna.
