| 内容記述 | In Japan, plans for a demonstration SPS experiments were proposed from the Ministry of Education, Culture, Sports, Science and Technology (MEXT), and the Ministry of Economy, Trade and Industry (METI). In the METI's plan assumes that existing launch technology will be used for an early actual proof. In this demonstration satellite, due to the limit of transmitting antenna size and generation of power, power flux density on the ground (PFD) becomes about 0.3 W/sq m. This satellite assumes a subrecurrent orbit and its altitude is 370 km. For this reason, it is considered that the rectenna site is constructed in the place where the satellite passes the zenith. The lowest operation power density of conventional rectenna was about 100 W/sq m, so, present power density is not the sufficient strength so that rectenna may operate. So, receiving power can be increased by using parabola antenna, however, the power reception time from the satellite drastically decreases, since the beam profile becomes pencil beam. In order to lengthen the power reception time, an elliptical beam with wide-angle directivity in the satellite's direction of movement, and narrow directivity perpendicular to it is desired. A rectangular parabola rectenna with an elliptical beam was proposed, which can be formed by changing the reflector's rectangular shape and the directivity of the primary feed. A theoretical analysis was performed by the PO method and confirmed its validity using experiment. The target antenna gain was set to 32 dBi, and it is a condition for applying sufficient input power to the rectifying circuits. The - 3 dB beam width was designed +/- 4 degrees for the major-axis direction. The calculated antenna gain and the aperture efficiency were 32.0 dBi, 48 percent, respectively. Since, this value changed to 31.8 dBi and 46 percent in the experiment, respectively. For low input power flux density, good low input power characteristic rectifying circuits were adopted. The maximum value of the present rectifying circuit efficiency was 75 percent for a 350-mW input. From these data, it was proven that the efficiency of rectenna could be expected to about 33 percent. It is considered that this value is an enough practicable value, when the power density is low with 0.3 W/sq m is considered. | |||||||||||||
