Multi-mode antenna and method of controlling mode of the antenna
First Claim
1. A multi-mode antenna comprising:
- power supply lines;
a radiation unit having one or more array antennas that have an antenna effective opening surface and a direction of an antenna beam pattern, the radiation unit being capable of selectively changing the antenna effective opening surface and changing the direction, wherein each of the array antennas comprises one or more sub-array antennas that are each independently connected to a respective one of the power supply lines and each sub-array antenna comprises one or more unit element antennas;
an active channel unit connected to the one or more array antennas of the radiation unit, the active channel unit includinga plurality of switches,a plurality of transmission channels,a plurality of receiving channels, anda signal combiner and splitter; and
a modem and control unit connected to the active channel unit and having a control unit and a modem,wherein in the active channel unit,the switches are separately arranged to the power supply lines,the transmission and receiving channels are connected to the switches to perform amplification and phase control of signal power of one or more signals that are then output therefrom, andthe signal combiner and splitter combines and splits signal power of one or more signals for being input to or one or more of the signals that are output from the transmission and receiving channels, andthe control unit electrically and mechanically controls the array antennas and the modem modulates/demodulates a transceiving signal.

Abstract
Provided is an antenna for a base station and a repeater capable of electrically or mechanically controlling the individual operation of an element antenna constituting an array antenna or a sub-array antenna so as to adaptively cope with the change in the communication environment, and having an economic and high performance transmitting and receiving function, and a method of controlling a mode of the antenna. The multi-mode antenna includes a radiation portion having one or more array antenna and capable of selectively changing an antenna effective opening surface and changing a resistance direction of an antenna beam pattern, an active channel portion connected to the array antennas and including switches, transmission and receiving channels, and a signal combiner and splitter, and a modem and control portion connected to the active channel portion and having a control portion and a modem.
