COMPOSITE ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide the composite antenna whose design can easily be changed so as to reduce time and cost. SOLUTION: A radiating electrode 2 is placed on an upper face of an insulation layer 1 to form an antenna 3. A slit 4 is provided to the radiation electrode 2 to form an antenna installation section 5 on the upper face of the radiation electrode 2 surrounded by slits 4. Another antenna 3 is fixed to the antenna installation section 5. The antenna 3 and the other antenna 3 may respectively be formed separately. Moreover, an amplifier circuit may be formed on a lower face of the lowermost antenna.
