Liquid crystal antenna and communication equipment

The invention discloses a liquid crystal antenna and communication equipment, a first dipole radiation electrode directly couples a received microwave signal to a first electrode and a second electrode which are vertically arranged below the first dipole radiation electrode, and the first electrode and the second electrode form a differential line pair structure; the first dipole radiation electrode and the second dipole radiation electrode are arranged on the liquid crystal layer, namely, signals transmitted on the first electrode and the second electrode on the upper portion and the lower portion of the liquid crystal layer are the same in amplitude, the phase difference is 180 degrees, equal-amplitude differential-mode signal feed-in on the first electrode and the second electrode is achieved, and the liquid crystal antenna can directly receive microwave signals from the first dipole radiation electrode to form differential-mode signal feed-in. A balun does not need to be adopted to generate a differential
