| Abstract: | LNBF is an important part of satellite TV receiving system. The uniformity and effective suppression to the re-flected wave should be guaranteed while LNBF is tested. LNBF far-field measurement system is introduced in this paper. Theelectric field variable quantity and field strength difference between two orthogonal polarizations in LNBF effective volume weremeasured. The tested data of field reflected wave suppression quantity was analyzed. The field uniformity and effect of reflectedwave rejection were verified. The theoretical analysis and testing results show that the test site for far-field measurement systemcan meet the requirements of testing LNBF. |
