The invention provides an antenna unit and electronic equipment and relates to the communication technology field. The antenna unit comprises a metal plate which is provided with a groove, a feed probe, a metal sheet which is arranged in the groove and forms orthogonal differential feed, wherein the feed probe penetrates through a bottom of the groove and is connected with the metal sheet througha feeder line, and the feeder line is a bent feeder line. In the scheme, the metal plate is served as one part of the antenna unit, an influence of the metal plate on antenna performance can be avoided, and an wireless experience of a user in multiple frequency bands during global roaming can be improved; the metal sheet of orthogonal differential feed is formed in the groove, an MIMO function ispossessed so as to improve a transmission rate of data, dual polarization can be formed, a wireless connection capability of the array antenna is increased, a probability of communication disconnection is reduced, a communication effect and the user experience are improved; and the feeder line is bent so as to connect the feed probe with the metal sheet, and related variables can be adjusted to carry out impedance matching.
