<p>A paraelectric transmission line layer (102) and a ferroelectric transmission line layer (105) are laminated through a ground conductor (107), and plural phase shifters which are connected via through holes (108) that pass through the ground conductor (107) are disposed on both of the transmission line layers at some positions on a feeding line that branches off from the input terminal between all antenna terminals and an input terminal to which a high-frequency power is applied. In addition, loss elements each having the same transmission loss amount as the phase shifter, or the phase shifters are disposed so that transmission loss amounts from all of the antenna terminals to the input terminal are equalized.</p><p>Accordingly, an antenna control unit which can be manufactured in fewer manufacturing processes and has a pointed beam and a large beam tilt amount, and a phased-array antenna that employs such antenna control unit can be obtained.
