Abstract

The present invention relates to a reconfigurable hybrid antenna device. According to the present invention, the reconfigurable hybrid antenna device includes a reflective plate that reflects an incident signal and a reconfigurable power supply arrangement that includes one or more element antennas for supplying power to the reflective plate. The reconfigurable power supply arrangement has characteristics of electrical reconfiguration and physical reconfiguration of the element antennas, and reconfiguration of changing a range of radiation of signal powers radiated from the element antennas. With these characteristics of reconfiguration, it is possible to simultaneously or independently provide a plurality of mobile communication services physically using one antenna, such that it is possible to have an economical base station antenna and considerably reduce the number of temporary base stations, thereby reducing the maintenance cost of base stations.

Claims

1. A reconfigurable hybrid antenna device comprising:

a reflective plate that reflects an incident signal;

a power supply arrangement that includes a plurality of element antennas for supplying power to the reflective plate;

active channels that control the levels and phases of signal powers radiated from the element antennas of the power supply arrangement; and

a controller that is connected with the active channels and outputs control values for the levels and phases of signal powers that are inputted and outputted to/from the element antennas to change a range of radiation of the signal powers radiated from the element antennas.

2. The device of claim 1, wherein the controller turns on/off the element antennas of the power supply arrangement.

3. The device of claim 1, wherein the power supply arrangement includes a plurality of element antennas that are activated within a multiband or a wide band.

4. The device of claim 3, wherein the controller turns on element antennas that are spaced apart by a distance from each other such that the element antennas have an electromagnetic effect on each other to form one integral beam pattern, in the plurality of element antennas.

5. The device of claim 3, wherein the controller turns on element antennas that are spaced apart by a distance from each other such that the element antennas do not have an electromagnetic effect on each other to form two or more different beam patterns, in the plurality of element antennas.

6. The device of claim 1, wherein the power supply arrangement changes the distances between the element antennas of the power supply arrangement.

7. The device of claim 6, wherein the power supply arrangement includes element antennas that are spaced apart from each other such that element antennas have an electromagnetic effect on each other to form one integral beam pattern.

8. The device of claim 6, wherein the power supply arrangement includes element antennas that are spaced apart from each other such that the element antennas do not have an electromagnetic effect on each other to form two or more different beam patterns.

9. The device of claim 1, wherein the surface of the reflective plate is formed in one dimension or two dimensions.
