Abstract :
Decreasing width and increasing gain on the main lobe of parabola antenna are important tasks in design. This paper discusses choke restraining on back radiation of parabola antennas. It improves radiation performance of the parabola antenna excited by circular waveguide. A model is designed and solved by PO and MOM and the results are identical with measured data.
