Abstract
This chapter presents the basic principles and recent developments of beamscanning leaky-wave antennas. The single radiating element is realized by modifying waveguides to leak along the structure producing radiated beams that scan as the operating frequency is varied. This unique characteristic distinguishes leaky-wave antennas from other types of antenna. Leaky-wave antennas are broadly classified into three classes: uniform, periodic, and quasiperiodic. In the following sections, each class will be explained and compared. Samples of novel design techniques and potential applications are also highlighted.
