SKELETON SLOT RADIATOR AND MULTI-BAND PATCH ANTENNA USING THE SAME

摘要

PURPOSE: A skeleton slot radiator and a multi-band patch antenna are provided to achieve improved impedance characteristics, while maintaining radiation patterns uniform. CONSTITUTION: A multi-band patch antenna comprises a skeleton slot radiator(75) which resonates in multiple bands and radiates wave; a reflector plate(71) for reflecting the wave radiated from the skeleton slot radiator; a feeder unit for feeding signals to the skeleton slot radiator; a spacing unit for spacing the gap formed between the feeder unit and the reflector plate; and a disconnection unit for grounding the skeleton slot radiator so as to stabilize the distribution of the current of the skeleton slot radiator.
