Array antenna capable of controlling antenna characteristic |
摘要 |
An array antenna includes a feeder element, a parasitic element implemented by a slot line, a variable capacitance element, and a directivity switching unit. The variable capacitance element is loaded in the slot line. The directivity switching unit supplies a control voltage to the variable capacitance element in order to vary the capacitance, and switches directivity of the array antenna.
