Microstrip antennas have a large number of applications despite their limitations. In some cases, pattern or bandwidth requirements can only be met with planar antennas that are not a traditional microstrip configuration. We will generally refer to these as printed or planar antennas. In some instances, microstrip transmission lines may be integrated with an antenna and so it is often still called a microstrip antenna. In this chapter, we will investigate a number of useful printed/microstrip antenna designs.
