Abstract: Embodiments of the present disclosure provide a power distribution network, a liquid crystal antenna including the power distribution network, and a communication device including the liquid crystal antenna. The power distribution network is configured to be used in a liquid crystal antenna and includes a plurality of cascaded power distributors. Each of the plurality of cascaded power distributors comprises a first microstrip line, a transmission medium region and a reference electrode. A tangent value of a dielectric loss angle of a transmission medium in the transmission medium region is smaller than a tangent value of a dielectric loss angle of a liquid crystal in the liquid crystal antenna.
