Abstract: Provided are antenna arrays based on three-dimensional special-shaped wave-absorbing structures by the disclosure, and includes an antenna array fixing plate and a plurality of antenna array units, where the antenna array units are sequentially fixed on the antenna array fixing plate; each of the plurality of antenna array units includes an antenna transmitting channel, two antenna receiving channels and a pair of three-dimensional special-shaped wave-absorbing structures; the antenna transmitting channel is used for transmitting antenna signals; the antenna receiving channels are used for receiving the antenna signals; and the three-dimensional special-shaped wave-absorbing structures are used for isolating antenna signals of antenna transmitting channels of other antenna array units.

Abstract: The present disclosure relates to a wearable electrical ankle pump massage bidirectional exerciser. The adopted technical solution is that the wearable electrical ankle pump massage bidirectional exerciser includes a vamp plate and a calf plate. A base is rotatably connected to a lower side of the vamp plate, a swing airbag for driving the vamp plate is arranged on an upper part of a rear side of the base, side supporting plates are arranged on both sides of the vamp plate, and side massage airbags are arranged on both sides of an upper part of the calf plate. An equipment box is provided on a bottom of the base, a first air pump group is arranged inside the equipment box, and the first air pump group is configured to drive the swing airbag and the side massage airbags.
