摘要：
An antenna unit is provided with: steerable antennas, each having one active antenna element and two parasitic antenna element; and metal blocks. Each of the active antenna elements is associated with at least one of the metal blocks such that the metal block is disposed remote from the active antenna element by a predetermined distance and operates as a reflector for the active antenna element. Each of the parasitic antenna elements is provided with a switching circuit for changing an electrical length of the parasitic antenna element, and the parasitic antenna element operates as a reflector for an active antenna element of the same steerable antenna as the parasitic antenna element by changing the electrical length using the switching circuit.
