MULTI-BAND ANTENNA

摘要

PURPOSE: A multi-band antenna is provided to implement different frequency bands by selectively mixing a plurality of radiator patterns. CONSTITUTION: A multi-band antenna comprises a main radiator pattern(110), a low frequency radiator stub(230), and a high frequency radiation stub(220). A first radiator pattern with a low frequency band property is formed in one side of the main radiator pattern. A second radiation pattern with a high frequency band property is formed in the other side of the main radiator pattern. The low frequency radiator stub is selectively connected to the predetermined region of the first radiator pattern in order to diversify the frequency band property of the first radiator pattern. The high frequency radiation stub is selectively connected to the predetermined region of the second radiation pattern in order to diversify the frequency band property of the second radiation pattern.
