ANTENNA REQUIREMENT Optimization of the Acid Catalyst Concentration for Synthesis of Anti‐Cancer Agent Gamavuton‐0 by Using Mathematical and Statistical Software

Figure . measured result of axial ratio Axial ratio means the ratio between major axis and minor axis of ellipse polarization. Therefore, in ideal circular polarization, this value should be . n ideal linear polarization, the value becomes infinite. Generally, the wave that has axial ratio under dB of axial ratio is defined as CP by EEE. The bandwidth used in on‐board SAR mission is Gz to .8Gz. For that reason, axial ratio need to be less than dB from Gz to .8Gz. owever, every module could not achieve this requirement except for No . Especially, No. and No. have worse characteristic. Their axial ratio could achieve only half of requirement. Comparing No. which could achieve requirement roughly and them, there is big difference of characteristic. Figure . measured result of gain Result of gain is shown in fig. . n the measurement results of gain, although noise during measurement is observed, satisfying result was obtained in used bandwidth of 8 Mz. owever, only No. indicated different characteristic among six modules. Finally, results of radiation pattern are shown in fig. . Radiation pattern is measured in three points of Gz, . Gz and .8 Gz in each module . n on‐board SAR mission, tilt angle of degrees is required. Fig. shows all module can have the tilt angle and achievement of requirement. 0. 1 1. 2 2. 3 3. 4 4. 8.0 8. 9.0 9. 10.0 10. aial r at io [ dB] fre uency[GHz] No1 No2 No3 No4 No No ‐30 ‐20 ‐10 10 20 30 8.00 8. 0 9.00 9. 0 10.00 10. 0 Gain [ dB] Fre uency [GHz] No1 No2 No3 No4 No No a b c d e f Figure . result of radiation pattern a No. b No. c No. d No. e No. f No. -40 -30 -20 -10 30 60 90 120 150 180 210 240 270 300 330 9.0GHz 9.8GHz 9.4GHz -40 -30 -20 -10 30 60 90 120 150 180 210 240 270 300 330 9GHz 9.4GHz 9.8GHz -40 -30 -20 -10 30 60 90 120 150 180 210 240 270 300 330 9GHz 9.4GHz 9.8GHz -40 -30 -20 -10 30 60 90 120 150 180 210 240 270 300 330 9GHz 9.4GHz 9.8GHz -40 -30 -20 -10 30 60 90 120 150 180 210 240 270 300 330 9GHz 9.4GHz 9.8GHz -40 -30 -20 -10 30 60 90 120 150 180 210 240 270 300 330 9GHz 9.4GHz 9.8GHz
