Abstract: In a direction control antenna, a plurality of impedance elements are connected between a ground body and a radiator, a plurality of switches are connected between each impedance element and the ground body, and on/off of a plurality of switches is controlled according to a control instruction from the outside. In this case, by the turned-on switch, a radiation direction and a radiation form are determined according to short circuit positions of the radiator that is short-circuited to the ground body and the number of short circuit positions.

Abstract: An omnidirectional antenna is provided. The omnidirectional antenna includes a spiral antenna including a substrate, at least one upper antenna pattern formed on the substrate, and at least one lower antenna pattern formed under the substrate and connected to the upper antenna pattern; and a monopole antenna that supports the spiral antenna and that is connected to the spiral antenna. Therefore, by forming an omnidirectional antenna in a spiral antenna having an upper antenna pattern and a lower antenna pattern at an upper surface and a lower surface, respectively, of a substrate, three-dimensional current flow is available and thus omnidirectional radiation characteristics may be exhibited.
