INTERNAL ANTENNA FOR FREQUENCY TRANSFORMATION USING SUB ANTENNA

摘要

PURPOSE: A built-in antenna for conversing frequency is provided to converse an operating frequency zone of a main antenna by inserting a sub antenna into an inserting unit of the main antenna. CONSTITUTION: A built-in antenna includes a main antenna(100) and a sub antenna(200). The main antenna includes a main antenna pattern(110) and a main carrier(120). The main antenna pattern is made of a main radiation pattern, an feeding pattern and a connectivity pattern. The main radiation pattern radiates an electromagnetic wave signal. The urgent telegram pattern is formed on the one end of the main radiation pattern to change suddenly signal. The connectivity pattern is formed on the other end of the main radiation pattern to connect with the sub antenna. An insertion unit is formed on the single-side of the main carrier. The sub antenna is inserted to the insertion unit of the main carrier.
