The isolation between antennas needs to be considered when integrating antennas on vehicles, since poor isolation between antennas can cause interference between radio systems on-board. The electrical size of vehicles at gigahertz frequencies often limits the usage of full-wave methods. This paper therefore evaluates two efficient methods to approximate the antenna isolation; the non-singular transmission...
Calculating the mutual coupling between antennas on vehicles using full-wave simulations requires a vast amount of computer resources due to the electrical size of the structures. We therefore propose an alternative and approximate method to determine mutual coupling between antennas on vehicles for the case where there is line-of-sight (LOS) between the antennas. The proposed method is based on approximating...
In this paper we compare radiation patterns and mutual coupling in finite and infinite square lattice arrays of dielectric resonator antenna (DRA) elements. The array elements are cavity backed, slot fed cylindrical DRAs that utilizes the HE11δ mode. It is observed that the degree of the mutual coupling for non-edge elements is very close to the mutual coupling between the corresponding elements in...
