Abstract
A new leaky-wave antenna was presented and discussed in Part I that possesses many desirable performance features. The antenna structure is also simple in form, consisting of a rectangular waveguide with an offcenter stub on its top wall. Part I presented the principle of operation and the basic theory in which the stub guide was idealized to be infinitely long (or high) in order to stress the essential features. In practice, however, the stub guide has a finite length (or height) and it may be terminated by a flange or a ground plane or simply remain in the form of a pair of baffles. The modifications in the theory and the associated performance considerations under these practical circumstances are treated in this paper.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
