Electromagnetic compatibility (EMC) modeling of complex onboard antennas is really a challenge in computational electromagnetics (CEM), especially in the presence of electrically large platforms. We usually face an electromagnetic system consisting of multi-scale structures, and it is almost impossible to handle the whole system with just one CEM method. Even though we turn to hybrid methods, such...
The modern graphics processing unit (GPU) programming technique is applied to speed up the simulation of the performance of GPS antenna installed on a self-driving car in practical environments with the method of moments (MoM) and physical optics (PO) hybrid technique. To take good advantage of GPU acceleration, the MoM part, ray tracing, PO current calculation, and post processing are all executed...
A new and general hybrid scheme consisting of the method of moments (MoM) and the physical optics (PO) is presented for the efficiently modeling of complex antennas installed on large-scale platforms. Different from the conventional MoM-PO, the proposed general hybrid technique is more flexible to handle arbitrary onboard antennas by integrating preprocessed data of antennas into the hybrid scheme...
A method of moments (MoM) and closed-form Green's function approach are employed to characterize the radiation pattern of a center-fed helical microstrip antenna mounted on a superstrate of a circular conducting cylinder. An analytic expression for the current on the helical microstrip antenna is rigorously obtained by solving a mixed potential integral equation (MPIE) in the spatial domain. With...
