Flush-mounted piggyback microstrip antenna

摘要

A dual radiating system where one radiating element is placed atop the other in a piggyback fashion. The elements can be a pair of microstrip or dielectric-loaded parallel plate radiators, or it can be a combination of the two. Separate coaxial lines feed each of the radiators, and there is a minimum of coupling from one antenna to another. The antenna can be used alone or more effectively in a linear or planar conformal array.
