| 内容記述 | Last year, we have proposed 24GHz satellite MPT experiment for the SPS. The biggest weak point of the SPS is its huge size which is decided by the theory of microwave beaming andeconomical reasons. The same weak point is on the satellite MPT experiment as the first step to the SPS. We can not transmit enough microwave power with GHz order frequency from the experimental satellite to ground. It is because our proposal of 24GHz satellite MPT experiment.We revised the 24GHz rectenna to increase the RF-DC conversion efficiency. We add the adjust stub and resonator after the diode. The resonator is put after the adjust stub and consists of high impedance line (120 Omega) and DC pad. As a result, the RF-DC conversion efficiency increases to 54.2％ at 130mW, 400Omega, 5.6V. In next step, we use 12-way power divider between the antenna and the rectifying circuits to increase a received power. We can receive and rectify twelve times larger power in the new rectenna than in one rectenna element. The return loss of the developed 12-way power divider is -19.1 dB and the pass losses are -0.15 dB of the minimum and -0.46 dB of the maximum. We developed 500mW rectenna at 24GHz with the power divider. The RF-DC conversion efficiency decreases to 43.6% at 500mW, 40.2Omega. In this case, VSWR of the waveguide is 2.25 and it is larger than in the previous experiments. We consider this is one of the reasons of low efficiency.We have to realize the SPS and its experimental satellite at all costs for future. We hope this experimental results lead to the experimental satellite for theSPS. | |||||||||
