Abstract

The invention relates to the field of radio technologies and particularly relates to a dielectric lens antenna for a high-altitude platform communication system. The dielectric lens antenna for the high-altitude platform communication system is used for solving the problems of large mass, big volume and complicated manufacture process of the antenna for the high-altitude platform communication system nowadays. A dielectric lens ball is connected with a dielectric slab of a yagi antenna unit, and the dielectric lens ball and the dielectric slab of the yagi antenna unit are integrally formed; balanced microstrip lines are adopted to feed the antenna; a second balanced microstrip line for feeding is arranged on the rear side wall of the dielectric slab; one end of a first balanced microstrip line for feeding is connected with one of two active oscillators; the other end of the first balanced microstrip line for feeding is simultaneously connected with two reflectors; and a horizontal section of the second balanced microstrip line for feeding is connected with the other one of the two active oscillators through a metal filler. The dielectric lens antenna has the characteristics of wide band, high gain, strong directional radiation property and narrow beam width, and can be applied to prospective high-altitude platform communication systems.

Description

Technical field [0001] The invention relates to the field of radio technology, in particular to a dielectric lens antenna that can be used in a high-altitude platform communication system. Background technique [0002] At present, the wireless communication system has developed in the direction of higher spectrum utilization, larger system capacity and more flexible network coverage. As a new mobile communication method, the high-altitude platform communication system has small free space attenuation and short delay time compared with synchronous satellites; compared with terrestrial cellular systems, its coverage area is large, and its channel fading and transmission power are also low. Can be significantly reduced. At the same time, the high-altitude platform communication system has high flexibility, does not require a complex and large launch base, can also be quickly transferred, and can be used for monitoring and communication in areas where natural disasters occur.
