Arbitrarily polarized microwave power transmission technologies including polarization auto-matching retrodirective transmitting method and arbitrarily polarized microwave rectenna are proposed in this paper. The polarization auto-matching retrodirective transmitting method using phase conjugating circuits and polarization rotators can receive any polarized pilot signal and generate predictable polarized...
This paper presents a microwave power transmission demonstration system comprehensively simulating the operating mode and validating the functions and efficiency of microwave power transmission technologies for SSPS (Space Solar Power Station). The transmitting antenna array is a planar microstrip antenna array with quasi-Gaussian distribution. The beam collecting efficiency of this system is about...
A polarization auto-matching retrodirective method is proposed in this paper. Using phase conjugating circuits and polarization rotators, it can receive any polarized pilot signal and generate predictable polarized beam aimed back to the rectenna. Phase conjugation with heterodyne mixing is executed twice to lower LO frequency and reduce phase error. The polarization mismatch loss and interference...
To release pressure of solar power satellite engineering, a concentric disc system model is put forward here. Classical Sandwich structure is abandoned for different requirement for planar accuracy between solar array and microwave power transmission array. The solar array is mounted with solar cell on both sides to reduce the system power dynamic range. The microwave power transmission disc circumrotates...
This paper presents a calibration method used to compensate channel amplitude and phase mismatch of the retrodirective antenna array for microwave power transmission. The calibration algorithm of N elements array antenna involves transmission of N time multiplexed orthogonal encoded signals. The received signals are coherently detected, accumulated in vector forms, and a set of correction factors...
The solar power satellite (SPS) will serve as an important energy source in the future and many models have been investigated around the world. Microwave power transmission (MPT) is one of the most important technologies of a SPS system. A large power generation and transmission panel is often considered with emphasis in MPT research. Active integrated antenna (AIA) can be employed to construct such...
The solar power satellite (SPS) is potentially an important energy source in the future and many models have been investigated around the world. Microwave power transmission (MPT) is the pivotal technology of a SPS system. A large power generation and transmission panel is often considered with emphasis in MPT research. Two architectures may be to construct the space segment of the MPT system. For...
