Abstract: The present application discloses a multi-input multi-output antenna and a system. The multi-input multi-output antenna includes a plurality of stacked oscillator layers. The oscillator layers include a supporting plate and an antenna array disposed on the supporting plate. Each of the oscillator layers is connected by a plurality of connecting members, and a spacing between the oscillator layers is at least 0.9, which is a wavelength of center frequency of the multiple-input multiple-output antenna.

Abstract: The present disclosure relates to a three-dimensional-layout high gain radio-frequency front end apparatus, including an antenna device and a radio-frequency transceiver device. The antenna device includes two or more antenna array layers arranged in layers. The radio-frequency transceiver device includes a filter, a circulator, a receiver and a transmitter. The antenna array layer is connected to a filter. The filter is connected to a circulator by an optical fiber, and the circulator is connected to a receiver and a transmitter respectively by an optical fiber.
