IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 56, NO. 10, OCTOBER 2008 3143 LeakyWave Slot Array Antenna Fed by a Dual Reflector System Mauro Ettorre, Member, IEEE, Andrea Neto, Member, IEEE, Giampiero Gerini, Senior Member, IEEE, and Stefano Maci, Fellow, IEEE AbstractA leakywave slot array antenna fed by a dual offset Gregorian reflector system isA procedure is described for designing dual reflector antennas. The analysis is developed by tak ing each reflector to be the envelope of its tangent planes. The slopes of the emitted rays are speci fied rather than the phase distribution in the emit ted beam. dual reflector antenna system

An ellipsoid dualreflector antenna system satisfying the Mitzuguchi condition eliminates the crosspolarization component. By replacing the typical dual reflector system's main reflector with two orthogonally polarized surfaces, two orthogonal linear polarization beams can be produced, each one retaining high crosspolarization performance.

Cassegrain antenna. The beam of radio waves from the feed illuminates the secondary reflector, which reflects it back to the main reflector dish, which reflects it forward again to form the desired beam. The Cassegrain design is widely used in parabolic antennas, particularly in large antennas such as those in satellite ground stations, A compact, complex, tracking system ensures that the antenna keeps pointing at the satellite while the vehicle is on the move.

This is the first truly comprehensive and most uptodate handbook available on modern reflector antennas and feed sources for diversified space and How can the answer be improved? Dualreflector antennas are based on principles that have been used in optical telescopes for centuries, with Cassegrain and Gregorian telescopes dating back to the late sixteen hundreds. These antennas share many of the underlying principles of operation with typical singlereflector structures. This antenna offers a dual offset reflector design that incorporates precisionformed panels, contoured radials and a machined hub assembly. The stateoftheart design provides exceptional performance for low crosspolarization levels and excellent sidelobe patterns.
