Abstract
A liquid crystal antenna unit and a liquid crystal phased array antenna are provided. The liquid crystal antenna unit includes: a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first substrate and the second substrate, a transmission line on a first surface and extending in a first direction along the first surface, a first antenna oscillator on the first surface and arranged as an elongated dipole extending in a second direction along the first surface, a second antenna oscillator on a surface of the second substrate distal to the first substrate and at a position corresponding to the first antenna oscillator, and a ground electrode on a surface of the first substrate distal to the second substrate.
