Printed circuit antennas are being used on a variety of spacecraft, aircraft, and projectiles where their low profile and conformability minimize interference with the structural and aerodynamic properties of the vehicle. The basic microstrip antenna has been studied extensively, but some important aspects of its performance are not yet characterized by the analyses that are available to the designer. Furthermore, new applications in millimeter wave monolithic phased arrays are forcing the designer to use substrates that are electrically thick and that may have a high permittivity. This paper describes several characteristics of microstrip antennas and identifies some that are being studied with the aim of improving antenna performance. A brief description of analysis techniques available to the designer and researcher will be presented. Finally, several aspects of monolithic and integrated phased arrays will be considered. General properties of these arrays will be discussed, and then several architectures and their associated printed circuit radiators will be presented.
