Abstract
The invention discloses a foldable corner reflector antenna, which is provided with a binary symmetric oscillator array, a one-to-two power divider and a foldable corner reflector. The binary symmetric oscillator array is formed by a first active oscillator and a second active oscillator, which are in collinear arrangement. The foldable corner reflector is arranged behind the binary symmetric oscillator array; the axis of the binary symmetric oscillator array is parallel with the axis of the foldable corner reflector; and the one-to-two power divider is arranged in the center of the axis of the foldable corner reflector to feed the symmetric oscillator array. The antenna adopts a reflector structure with a reflecting grating and a reflection net being combined, thereby realizing directionality of antenna radiation, ensuring the antenna has higher gain and larger front-to-rear ratio, and meanwhile, reducing wind resistance and reducing antenna weight. The foldable corner reflector structure can be folded at the axis of the foldable corner reflector, so that convenient transport and repeated construction are realized; the antenna is simple in structure and convenient to use; and the antenna has wide application value in the aspects of television reception, communication and radar and the like.
