Reduction of mutual coupling between two dielectric resonator antennas mounted on a circular cylindrical ground plane

2010 IEEE Antennas and Propagation Society International Symposium, 2010

The finite element method and the finite integration technique are used to calculate the radiation characteristics as well as the mutual coupling between the array elements. Mutual coupling reduction is obtained by cutting slots, or inserting quarter wavelength grooves in the surface of the cylindrical ground plane between the antenna elements.

By combining the desirable features of the method of moments (MoM) and wavelet packet transform (WPT) to analyze large-scale electromagnetic problems. The computational domain is divided into smaller and manageable sub-domains, with coupling between these sub-domains is taken into account. As a result, a considerable reduction in the computational time and required computer memory storage is achieved.

The effect of the radius of curvature on the return loss, input impedance, standing wave ratio, and radiation patterns is investigated. The finite element method and the method based on the finite integration technique are used to calculate the radiation characteristics of the antenna.
