This paper present an application of the Coherently
Radiating Periodic Structures - CORPS on the design of a Beam
Forming Network -BFN. The Named CORPS-BFN is a novel
feeding network with special behaviour characteristics that
allows several improvements compared with classical feeding
networks, such as, the reduction of necessary electronic to
control a phased array and the possibility to have several beams
very close to each other.
In this paper, an analytical comparison of CORPS-BFN with
both a Horn Antenna Array and a uniformly field distribution
antenna will be analyzed. This study shows how applying this
technology to a Multibeam antenna system the area necessary
to radiate 7 independent beams can be drastically reduced.

In this paper some possible
applications of the new philosophy to design antenna
systems based on the Coherently Radiating Periodic
Structures (CORPS) is presented.
This principle could allow the designer to simplify the
needed feeding network for many array antenna
systems since some elements could be coupled from
the neighbouring ones, keeping the original excitation
profile.
It will be also shown in this paper how the three
dimensional version of CORPS could be understood
as a focusing planar lens, since it is possible to
distribute the information of one element to many
radiating elements by using the coherent coupling
mechanism between all the elements of the whole
structure. With this configuration, many directive
beams could be really close to each other, increasing
the possibilities to handle high resolution in imaging
systems.
