Abstract:
PROBLEM TO BE SOLVED: To provide a wall embedded antenna system for indoor radio communication.
SOLUTION: The wall embedded antenna system is provided with a first AP antenna a part of which is embedded in at least one surface of any one selected wall indoors, an AP (RF unit) linked with the first AP antenna and a second AP antenna a part of which is embedded in other surface of any one selected wall and which is linked with the AP. In addition, the antenna system is provided with first antenna structure provided by passing through any one selected wall indoors and an AP (RF unit) linked with the first antenna structure, however, the first antenna structure consists of sliding structure which can be varied depending on thickness of the wall. By such antenna system regarding this invention, shift of a frequency band by walls is minimized and successful quality radio communication is supported wherever indoors a terminal is located. Then, intensity of an electric field is enhanced at a place where the terminal is located.
