Development Of Electrical Performance Analysis System Based On FEKO For Circular Parabolic Antenna

The system of electrical performance analysis based on FEKO for circular parabolic antenna has provided the effective exchange tool for the structural designers and the electromagnetism designers.It has overcome the mechanical and electrical separation flaw in the design stage of circular parabolic antenna, and has solved electrical performance analysis problem of distortive round parabolic antenna which has received the load function. It can accelerate the research and development of each kind of large-scale round parabolic antenna's design for the ground station system, and promote vigorous development of our country's aviation and the astronautics enterprise.In this paper,the author made secondary development of FEKO based on the script commands, realizing the parameters of finite element modeled in FEKO, meshed refinement, electrical parameter stetted and other functions, made FEKO can be analyzed and calculated the electrical performance for the round parabolic antenna by automated background. There has consummated the interface routine which transforms the model form ANSYS to FEKO, proposed a new way which is through the user controlling the parameters and making program generate the interface routine, to realize the processing universalized of the finite element grid model transformed from ANSYS to FEKO for the round parabolic antenna. In this paper the author developed the new electricity performance post-processing module in view of the FEKO post-processing module re-development function's insufficiency. It made electrical performance index parameter what the designers need to obtain when they simulate the round parabolic antenna they designed demonstrate on the contact surface conveniently with button's form, and caused the post-processing function becoming simple, direct-viewing and easy to use.In this paper the author developed a software system of electricity performance analysis based on FEKO for the round parabolic antenna, which based on structure analysis software ANSYS and high frequency electromagnetic field software FEKO of the integration software system. It realized to transform the round parabolic antenna model which deformed by the loads from ANSYS to FEKO, using physics optics (PO) calculating its electrical performance, and carried on intellectualized processing to the result. There is a good platform for the round parabolic antenna electricity performance analysis.
