| Abstract: |
| It is difficult to simulate the electromagnetic properties of high power divide
rs and high precision of calculation result is required for the el
ectrically large objects.According to above mentioned characteristics,an X-band
four-way electrically large high power divider i
s optimally designed based on BP(Back Propagation) neural network.The computatio
n cycle has been greatly shortened compared
with HFSS simulation. The test results measured by vector network analyser Ag
ilent N5244A indicate that the loss of every way is better than 6.8 dB, phas
e differenc
e is 2° at 92～9.6 GHz, which are in good accordance with simulation resu
lts of BP neural network.The method provides reference for the design of electri
cally large microwave circuits. |
