摘要：

Effects of ground plane and/or dielectric truncation on the radiation efficiency of a printed radiator are studied. A closed-form expression for the reflection coefficient of surface wave modes from the truncated edge is obtained. Numerical results of the reflection coefficient and the radiation efficiency and radiation patterns for various dielectric constants, substrate thicknesses, and ground plane dimensions are presented. It is found that for certain values of ground plane dimensions, the radiation efficiency is considerably lower than normal. These dimensions should be avoided to reduce the surface wave loss.
