- Disclosed are an apparatus and method for controlling a radiation direction of a small sector antenna, used for a small wireless transmission device having limited power and calculation capabilities, capable of operating at a low power consumption with the necessity of simple calculation capabilities or without the necessity of even a few calculation capabilities. The apparatus for controlling a radiation direction of a small sector antenna includes a plurality of capacitance blocks including a plurality of capacitors each having one end commonly connected to corresponding parasitic elements and having a different capacitance. Capacitors having a capacitance corresponding to a radiation direction are selectively connected to corresponding parasitic elements through a plurality of switching units and a controller, thereby simplifying controlling and reducing power consumption for controlling the radiation direction.
