一种层叠结构双频圆极化GPS天线的设计
The Design of Dual-band Stacked Microstrip Patch Antennas for GPS Applications
摘要
Abstract
It presents the design of a kind of novel and high-efficient dual-band stacked microstrip patch antennas,based on cavity model theory, the technology of sloting on the surface of the patch, and multiple feed points technology.. The property of the microstrip antennas has been numerically simulated using the Finite Difference Time Domain (FDTD) method. By simply tuning the size of the patch and the turning-stub, and inducing the redistribution of the power of the electric field, the production of resonance in the desirable frequency can be achieved. At the same time, the upper layer which is the parasitic element of the under layer is perforated for improving the symmetry of the radiation field and the radiation efficiency. These excellent features, including the small size, the wide band,and the easy achievement of dual-band circular polarization, make the design have promising prospects in the future of wireless communication.关键词
