内容記述 | In resent Space Solar Power Station/Satellite (SPS) design, a concept of 'unit' is adopted. For the SPS, a large number of the 'units' of microwave power transmission system are used. The each 'unit' had better have no connection electrically and in structure. One 'unit' is rigid, however, a transmitting antenna which consists of a large number of the 'units' is not rigid and it seems to be soft structure like a paper. A microwave beam pattern has to be considered in consideration of the soft structure of the unit-type SPS. For an analysis of microwave beam pattern, considered are the structure, an error of phase, and error of amplitude, a trouble of transmitter. Assumed are bent structure, whose units are connected with ratches, and separated structure, whose units are not connected with ratches. Also assumed is a small power satellite which is planed in USEF. It is assumed that a transmitting antenna of the small power satellite consists of 25 units whose size is 0.8 m and which includes 25 antenna elements with frequency of 5.8 GHz. A microwave beam pattern is analyzed with ID array. For an estimation of the microwave beam, a beam collection efficiency and maximum side lobe level are used. As a result a capacity of bent of the connected structure is below several degrees (= several cm) if high beam collection efficiency and low side lobe level are kept. A capacity of a distance of the separated structure is below a several mm if high beam collection efficiency and low side lobe level are kept. Also permitted is below 5 degrees as an error of phase between each antenna, below 1 degree as an error of phase between each unit, below 10 percent as an error of amplitude between each antenna, below 2 percent as an error of amplitude between each unit, and below 1 percent as a rate of trouble of antenna elements, respectively. The estimation is one example when the microwave beam pattern is estimated with power satellite parameters. However, it is concluded that more accuracy for the microwave power transmission is needed than that for a commonly used communication system. | |||||
