Abstract
An active antenna () comprising a driving loop with first () and second () sections, each of which extends between end points. Each end point of each section () is connected to the closest end point of the other section by a reflection amplifier (). One reflection amplifier () comprises differential ports for signals to/from the active antenna. The active antenna also comprises a passive loop with first () and second () sections, each of which extends between end points. Each end point of each section () is connected to the closest end point of the other section by a reflection amplifier (). The driving loop and the passive loop extend in parallel to each other and the first and the second section () of each of the loops form separated complementary parts of a closed geometrical shape and are built in open waveguide technology.
