An apparatus and method are provided for stabilizing terminal power in antenna ports. A data transmission/reception method is provided for terminal power stabilization in a communication system using multiple antennas. An optimal antenna immune to absorption loss due to human body proximity is selected from among multiple antennas connected to a single port when a data service is provided. Data for the data service is transmitted and received through the selected antenna.

Claims

1. An apparatus for stabilizing terminal power in a communication system using multiple antennas, comprising:

a predetermined number of antennas for providing a data service in different positions providing immunization to absorption loss due to a human body;

a combiner for connecting the antennas and providing data signal transmission and reception paths according to the data service ; and

a transceiver, connected to the antennas through the combiner using a single port, for transmitting and receiving a data signal.

2. The apparatus of claim 1, further comprising:

a discrete distributed structure, passively combined by the combiner, for reducing average power loss and impedance mismatch effects due to near-field loading effects.

3. The apparatus of claim 1, further comprising:

a continuous distributed structure, based on continuous antennas, for reducing average power loss and impedance mismatch effects due to near-field loading effects.

4. The apparatus of claim 1, wherein the combiner combines sub-elements for macro diversity.

5. The apparatus of claim 1, wherein the combiner has a combination structure for optimizing radiating efficiency by redirecting reflected power from one sub-element to another sub-element.

6. The apparatus of claim 1, wherein a combination pattern of the combiner is a cascade pattern mapped to short-term diversity and multiple-input multiple-output (MIMO).

7. A data transmission/reception method for terminal power stabilization in a communication system using multiple antennas, comprising the steps of:

selecting an optimal antenna immune to absorption loss due to human body proximity from among multiple antennas connected to a single port when a data service is provided; and

transmitting and receiving data for the data service through the selected antenna.
