What is it about?
An antenna design that produces a radiation beam which is directed along the length of antenna. The geometry of designed antenna makes it possible to be installed in a metallic platform.

Why is it important?
The bandwidth of a cavity backed antenna producing end-fire radiation is limited. A design has been presented in the paper which results in improved bandwidth performance compared to previous designs of this kind, while being consistent with the geometrical configuration of the previous designs.
Perspectives
Using a single cavity to design a slot array for end-fire radiation is a difficult task. The Q of cavity limits its bandwidth. There are other ideas of backing each slot by an individual cavity. However the simpler configuration is the earlier one i.e. single cavity backing all slots. Attempt has been made in the paper to produce a design with single cavity backing, end-fire radiation and with a bandwidth greater than previous designs of the same kind.
